Are Justin Bieber's latest nude photos just another below the belt blow in his ongoing feud with Orlando Bloom?
It's a (hard to believe) theory that has been doing the rounds since photos of the pop star's package leaked online just days after the Troy actor was snapped paddleboarding in his birthday suit.
Over the past few years, Bieber and Bloom's feud has become one of the most fierce in Hollywood.
It all began back in 2012 when the Sorry singer was rumoured to have gotten a little too close to Bloom's then wife, Miranda Kerr, at a Victoria's Secret show in New York.
In 2014, not long after a recently divorced Bloom was spotted getting cosy with Bieber's ex, Selena Gomez, the two famous fellas came to blows in Ibiza.
In a restaurant packed with celebrities, Bloom took a swing at the singer after Bieber allegedly made a comment about Kerr.
Bieber left the restaurant after the incident but continued to stir the pot on Instagram where he posted a photo of the Aussie model and then uploaded a picture of Bloom crying.
All was quiet between the pair until last week when Bieber may/may not have engaged in what can only be described as a d**k measuring contest with his famous foe.
But Bieber and Bloom aren't the only stars who quite clearly hate each other.
Here are some other celebrities who just can't seem to get along:
SHIA LABEOUF AND FRANKIE MUNIZ
Not surprisingly it was LaBeouf who fired the first shot in this feud.
Back in 2003 the Transformers star dissed the Malcolm in the Middle actor in an interview with Entertainment Weekly.
"I used to see him at premieres and stuff and it would always be like he was looking down on me," LaBeouf said.
In 2010, the LaBeouf had another crack.
During a radio interview, the mouthy star was asked what it was like to star in six consecutive films that all went to number one.
"While that's flattering as hell, you could have put Frankie Muniz into any of the movies I've been in and those movies still would've still been No. 1," he said.
Muniz responded on Twitter, writing, "Dear Shia LaBeouf, It's getting creepy the fact that you can't stop talking about me. It's been 12 years now. I don't know you. Thanks".
MARTHA STEWART AND GWYNETH PALTROW
Gwyneth Paltrow has received a lot of media attention for her lifestyle website, Goop.
But Martha Stewart is not impressed.
"She just needs to be quiet," the 75-year-old said to Net-a-Porter's Porter magazine last year.
"She's a movie star. If she were confident in her acting, she wouldn't be trying to be Martha Stewart."
Stewart sunk the boot in again when she published a recipe in November called "Conscious Coupling", a not-so-thinly veiled reference to Paltrow's "conscious uncoupling" from Chris Martin.
Rising to the challenge, Paltrow responded by publishing a recipe on Goop called Jailbird Cake, a reference to Stewart's stint in prison in 2004.
EMINEM AND MARIAH CAREY
The feud between these two Grammy winners can be traced back to 2002.
Eminem had revealed that he and Carey dated in 2001, but the Hero singer denied the relationship rumours during an interview with Larry King.
"I think I was probably with him a total of four times," she said, "And I don't consider that dating somebody."
Clearly annoyed by Carey's denial, Eminem continued to talk about their alleged fling in the press and said in a radio interview that they "did have a relationship for about a good six, seven months".
But by 2009 Carey had obviously had enough of the rumours and released a song called Obsessed, in which she painted Eminem as some kind of stalker.
Some of the lyrics, which Carey denied were about Eminem even though she dressed up as him in the song's music video, include:
Ohh, finally found a girl that you couldn't impress,
Last man on the earth, still couldn't get this.
A month later, Eminem fired back with an expletive-filled song called The Warning and boy, he did not hold back.
Some of the lyrics include:
Enough dirt on you to murder you
This is what the fu*k I do, Mariah it ever occur to you that I still have pictures?
Call my bluff and, I'll release every fu*kin thing I got
Including the voicemails right before you flipped your top
The feud's gone quiet over the past few years but knowing these two, it could flare up at any moment.
KANYE WEST AND TAYLOR SWIFT
Just in case you've been living under a rock for the past few months, these two music superstars aren't exactly best buds at the moment.
They had their first falling out in 2009 when Kanye West stormed the stage at the VMA Awards as Swift was accepting her award for Best Female Video.
He ripped the microphone out of her hands and told the crowd that Beyonce deserved to win the award because she had "one of the best videos of all time".
In the years since, West has apologised profusely for behaviour at the awards show and the two stars seemed to have buried the hatchet.
But then their relationship turned sour once again in February when West released his song Famous, which includes the lyrics:
I feel like me and Taylor might still have sex/Why? I made that b***h famous.
After TMZ reported that Swift approved the lyrics, one of her representatives released a statement denying that she'd given her blessing.
"Kanye did not call for approval," Swift's rep said, "But to ask Taylor to release his single Famous on her Twitter account".
"She declined and cautioned him about releasing a song with such a strong misogynistic message. Taylor was never made aware of the actual lyric, 'I made that b***h famous'."
West took to Twitter to set the record straight, writing, "I called Taylor and had an hour long convo with her about the line and she thought it was funny".
The back and forth continued with one of Swift's representatives again denying that West had cleared the term "b***h" with her.
"Taylor cannot understand why Kanye West, and now Kim Kardashian, will not just leave her alone," the rep said.
And then last month Kim Kardashian dropped a bombshell.
The reality star posted a video on her Snapchat account of the phone conversation between Swift and West in which the Bad Blood singer thanked the rapper for clearing some of the Famous lyrics with her.
"I really appreciate it," Swift can be heard saying in the video, "Like, the heads up is so nice!"
Not long after the video went viral, Swift took to Instagram to clarify that she was never told "he was going to call me 'that b***h' in his song".
"Being falsely painted as a liar when I was never given the full story or played any part of the song is character assassination," she wrote.
"I would very much like to be excluded from this narrative, one that I have never asked to be a part of, since 2009."
