Kevin Federline has accused Beyonce of having Botox injections and surgery, and her fans are unimpressed.

The 37-year-old DJ, who is best known for his three-year marriage to pop star Britney Spears, has taken to social media to accuse the Drunk in Love hitmaker of having Botox injections after she was seen on TV alongside her husband Jay Z at a boxing fight in Las Vegas.

Kevin tweeted: "She looked botoxed. (sic)"

He then followed up with a second message.

So sad when a beautiful woman chops and screws her face up w/Botox and surgery... #sawface

The comments enraged Beyonce fans, who came to her defense online, though there has been no official response from the star herself.

Many focused on the ex-backup dancers past, calling him washed up, and posting unflattering images of his former wife Britney Spears.

@kevinfederline so sad when a man has to criticize a beautiful woman to get people's attention.

Earlier this year, meanwhile, Kevin admitted his high-profile relationship with Britney was "chaos", adding that the attention they received was difficult to manage.

Kevin, who married Britney in 2004 and shares sons Sean Preston, 10, and Jayden, nine, with the pop icon said: "'It was fun, it was crazy, it was chaos...The limelight, the entertainment business, the lifestyle - period. When you're 25-years-old, how do you handle that? Nobody can prepare you."

Kevin is now married to former volleyball player Victoria Prince, with whom he has two daughters - Jordan, four, and 19-month-old Peyton.
