David Cross and Amber Tamblyn: Engaged!

Sisterhood of the Traveling Pants and House star Amber Tamblyn, 28, is engaged to longtime boyfriend David Cross, 47, her rep tells Us Weekly.

Age difference? Please.

You're only as old as you feel, are we right? And come on, 28 and 47 is pretty much nothing compared to Doug Hutchison and Courtney Stodden.

David and Amber have been together for years.

This will be the first marriage for Tamblyn, known for her lead role in the 2003-2006 series Joan of Arcadia, and the Arrested Development star.

The happy pair has yet to announce a wedding date or release any further details regarding their engagement. Congratulations to them both!
