Jennifer Aniston's husband will be the "luckiest man in the world", says her former co-star.

The stunning actress - who is single after failed relationships with ex-husband Brad Pitt, and boyfriends Vince Vaughn and John Mayer - deserves to settle down with the right man because she's such a "lovely" person.

James Michael Tyler - who starred with Jennifer in 'Friends' - said: "Jennifer's partner is going to be the luckiest man in the world. She is lovely, but she was more of a sister to me!

"She is just as beautiful on the inside as she is on the outside. There is genuine compassion that she has. She just glows."

Michael - who played Central Perk manager Gunther in the hit US TV series - also revealed how star-struck he was when Sean Penn made a guest appearance in 'Friends'.

He added to Britain's OK! magazine: "There were so many huge stars who guest starred in 'Friends'. I was floored by Sean Penn. I was really star-struck and a bit nervous. He walked up to me first and said, 'Hey, you're Gunther on the show. Man you do a great job.' I was just like, 'Thank you Sean Penn, I think you're pretty good, too!' "
