Gossip Girl’s Blake Lively appears on the Late Show with David Letterman on Tues., March 24.

“Julia Roberts called me this weekend and she wanted to know if we could take you away to a Polygamist community and marry you,” Blake told the newlywed Letterman. “But I heard that somebody snatched you up. So — the offer is open…”

Dave jokingly responded: “I’ll tell you something off the record, we’re not getting along. There is talk of a legal separation. I’ll be outside on the curb.”
