Jennifer Lopez is "gorgeous" and "fun", according to her 'What To Expect When You're Expecting' co-star Rodrigo Santoro.

The '300' actor loved working with the 'American Idol' judge in the film - in which they play a couple trying to adopt a baby - and he praised Jennifer for her generosity.

He told E! Online: "Jennifer was really great. She was very cool.

"She was really generous. She's incredibly professional and helped me a lot because I think she's got this natural talent for comedy. She is fun! She's gorgeous."

Rodrigo isn't Jennifer's only recent co-star who is full of praise for her, Jason Statham had only kinds words for the actress after working with her on 'Parker'.

The 44-year-old star admired the singer-and-actress' "terrific" ability while starring alongside her in the crime thriller movie - which is based on the book series by Donald Westlake, which revolves around a thief who is forced to become a killer - and he thinks the 'On The Floor' hitmaker is a ''tremendous actress".

He said: "She's a great person to work with, she's a lot of fun. Brilliant. She's terrific, she really is a tremendous actress."
