To add insult to injury, Tomei was also "extremely particular" and returned a lot of items.
Because Tomei is "one of my favourite actresses" Tamaran went "easy" on her and gave her a 5/10.
In another video Tamaran breathes fire at A-listers J.Lo, Alba and Heigl.
"If 2020 was a career, it would be Katherine Heigl. Friends of mine who have worked on set with her and photo shoots have told me that she is extremely difficult and always mad."
As for Alba, Tamaran says her friends that worked on set with her used the phrase "not nice".
"She loves to rub hummus on her dress, play mind games with you, [and] she does this thing where she talks to you while not talking to you."
Meanwhile, people who work for J.Lo aren't allowed to look at her and Tamaran added, "there's a reason why she can't hold down a costumier or a seamstress".
Pitch Perfect star Alexis Knapp was rated a meagre 1/10.
"There's some celebrities who pay, some who take forever to pay, and some who just don't pay because they think their name is enough. And out of the Pitch Perfect cast, that was Alexis Knapp," Tamaran, who worked with Knapp's stylist for a year, said.
Tamaran helped put together Knapp's outfit for the 2015 MTV Movie Awards.
"This was one of the most difficult looks to put together … Whilst being fitted in this dress, Alexis decided it would be wonderful to eat a slice of chocolate ice cream cake. Part of the cake melted onto the dress, and guess who had to clean it? Oh, but it gets better …"
Tamaran revealed that a designer had lent Knapp US$1300 worth of jewellery to wear on the red carpet and when it came time to return the jewels, Tamaran scoffs, "let's just say that she couldn't find it".
On top of it all, Knapp wanted all services for free.
"When my boss asked for payment, Alexis responded with, 'I needed to pay you?'" Tamaran said.
But it's not all doom and gloom in Hollywood. Tamaran calls out her favourite celebrities including Jon Stewart, George Clooney, and rates Carrie Underwood — "the sweetest woman on the planet" — a 10/10.
"[Underwood] looked into my eyes and said 'thank you, please, and have a good day'," Tamaran recalled, also praising Modern Family star Ariel Winter, who she said "is actually a really sweet girl. So was her family".
Winter only got a 7/10 because "we actually fitted her in a dress and tailored her in a dress that an agency wanted her to be photo opped in, but then she didn't even wear the dress."
Selena Gomez also got a shout out as a 10/10 for being "one of the most professional human beings in the industry. She actually acknowledges you and thanks you for your time and work."
