(Cover) - EN Showbiz - Scarlett Johansson has reportedly given her seal of approval to her ex-husband Ryan Reynolds dating Sandra Bulllock.

Sandra, 47, and Ryan, 34, are said to have grown their close friendship into a more romantic relationship and it's apparently not a problem for the Iron Man 2 star.

Scarlett is rumoured to have nurtured hopes of reconciling with Ryan after her summer fling with Sean Penn came to an end.

But now she realises that Sandra and Ryan are getting serious and she is wishing them well, Star magazine claims.

The former couple "really tried to save their marriage," an insider said before ultimately filing for divorce last December after two years together.

"Now that he's finally moving on too, she's happy for him, especially since he's with Sandra," a source told the publication.

Scarlett and Sandra apparently get on well and even playfully kissed during the 2010 MTV Movie Awards last June.

"Scarlett knows how much Ryan wants to be a dad and that while Sandra loves her career, she treasures motherhood more," an insider said.

"And Jesse [James] caused Sandra so much pain. Scarlett is sure Ryan would never hurt her that way. She feels the romance is good for them both."

Sandra divorced her husband Jesse after their five-year marriage imploded following revelations of his infidelity. (C) Cover Media
