David Beckham says it isn't easy sitting down to dinner with Tom Cruise and Katie Holmes.

"We were at dinner once with Tom and Katie ... and we sat there and everyone was like, 'OK, let's play a music game, let's start a singing game!'" Beckham, 34, recalled on George Lopez's TBS late night show, Lopez Tonight, Wednesday

Singing in public, he said, "is my worst nightmare!"

Beckham said he noticed one of his friends was dining at another table nearby.

"So I was texting my friend, 'Oh, please, invite me to your table!'" said Beckham. "I kind of get uncomfortable with that."

Kidding aside, Cruise, 47, and Holmes, 30, "are amazing parents and really good people," Beckham said. "You say there's good looking people, and you look at Tom, and he's one of the most handsome men I've ever met."
