Justin Long finds Drew Barrymore even "more beautiful" after working with her.

The 32-year-old actor - who has an on/off relationship with the actress - admits he discovered several wonderful new things about Drew when the pair filmed new movie 'Going the Distance' together.

When asked at the UK premiere of the romantic comedy at the Vue Cinema in London's Leicester Square last night (19.08.10) what his favourite thing about Drew is, he told BANG Showbiz: "I don't know if I can pick one thing. She's everything. She's beautiful and insanely funny and working with her I got to see a side of her that I hadn't seen before.

"I hadn't known her in a professional capacity before and the way she treats people on set just made her so much more beautiful."

Justin, 32, also admitted it made a pleasant change to work with someone he is close to on a movie rather than new people.

He said: "It's always easier working with people you know. Most of the time on set you're just hanging out anyway so it's nice to be around people you like."

Drew - who looked stunning in an Alexander McQueen khaki jumper dress and nude YVES SAINT LAURENT heels - admitted she was very excited to be in London promoting the project.

The screen beauty - who had the word "breathe" written on her left arm in large block capitals - said: "The people are lovely, stylish, sexy and fun. I love bringing films here and I feel so fortunate to be in London."

Drew, 35, and Justin, 32, also sparked speculation they are an item again by cuddling up to one another on the special blue carpet on the night.

Other stars to attend the premiere included Oliver Jackson Cohen - who appears in 'Going the Distance' - 'Captain America: The First Avenger' star Neal McDonough and Australian singer Gabriella Cilmi.
