Blair's New Boy Toy?

Memo to Chuck Bass: No one stands up Blair Waldorf. Because Queen B, whom we last saw taking off for Europe without a tardy Chuck, has already moved on.

A source tells People magazine that there's a new guy shooting scenes with Leighton Meester's Blair, named Marcus (Patrick Heusinger). "He's Blair's new love interest and Chuck's rival. Blair met him in Europe, introduced by Ben, whom she flew to Italy with after Chuck stood her up."

And yet, other scenes would imply that if Chuck and Marcus are rivals, the younger Bass is killing his prey with kindness. Spies told People that the pair was filmed for the show playing racquetball at the Eastern Athletic Club in Brooklyn Heights. After their match, Ed Westwick's Chuck and Marcus shook hands, then exchanged a phone number that Chuck programmed into his phone.

Hmm ... Friendly or conspiratorial? We'll have to wait and see!

Do you think Chuck and Blair are right for each other?
