Uinterview - u ask. they tell.

They may have been delighted to see each other, but by all reports they're still just friends. Ryan Reynolds, 34, and Sandra Bullock, 47, shared hugs and kisses on the red carpet of Reynold's new comedy, The Change-Up, costarring Horrible Bosses' Jason Bateman and Cowboys and Aliens Olivia Wilde.

Rumors started flying about a fling between the two single, sexy stars after they were divorced less than a year apart. Bullock's divorce from playboy Jesse James was finalized and Reynolds' marriage to Scarlett Johansson both fell apart in 2010, inspiring the Proposal costars and close friends to ring in the New Year together at Bullock's restaurant in Austin, Texas. Friends, drinks, and photographs were abundant, leading anyone with a sharp pair of eyes to catch the chemistry between the two.

On Monday night's premiere when Bullock surprised Reynolds on the red carpet, wearing a strapless black jumpsuit, The Green Lantern star beelined over to her, ignoring the press line for enough time to greet her with some friendly affection.
