Jennifer Meyer is All Smiles After Split From Tobey Maguire

Two days after Tobey Maguire and his wife announced their separation ... Jennifer Meyer is way past the ole sitting at home crying into a glass of red wine stage.

We got Jennifer leaving La Scala in Bev Hills Thursday afternoon, and asked her about the single life, and how she and Tobey are getting along. As we told you ... they've actually been apart since June, even though they just went public with it.

Check out the clip -- it appears Jen's caught a case of post-breakup hotness ... and happiness.
