Ewan McGregor and Jim Carrey visited a gay bar together.

The pair were seen enjoying 'Martini Tuesday' at Miami's Halo bar this week to research their new movie 'I Love You Phillip Morris', in which they play homosexual lovers.

A source said, "Jim and Ewan looked like they were having a great time. They were laughing and joking and looked as though they were really trying to get into character."

Jim stars as Texan convict Steven Marshall, who falls in love with his cellmate, Ewan's character Phillip Morris. He is inspired to attempt to break out of prison after Phillip is released.

This will not be the first time Ewan has played a gay character.

In the 1996 movie 'The Pillow Book,' Ewan starred as a bisexual man, and in 1998's 'Velvet Goldmine' he had to film a gay sex scene with 'Batman' star Christian Bale.

McGregor has two daughters, six-year-old Esther Rose and two-year-old Clara Mathilde with wife Eve Mavrakis. They also have an adopted four-year-old daughter Jamiyan.

Carrey has a 20-year-old daughter from his marriage to Melissa Womer. He is currently dating former Playboy Playmate Jenny McCarthy.
