Scarlett Johansson and Ryan Reynolds are making it official!

Johansson, 23, and Reynolds, 31, who have been dating since Spring 2007, are engaged, their rep confirms to Usmagazine.com.

Reynolds was engaged to singer Alanis Morissette. They split in February 2007 after four years together.

Johansson was previously dating Josh Hartnett.

In February, it was reported that the actress was seen shopping for wedding dresses at a Monique Lhuillier boutique in L.A. with her mother and sister.

But her rep told Us Weekly, "A family member is getting married, not her. She is not engaged."
