Gorgeous Ugly Betty Co-Star Alert: Brooklyn Decker

This is one way to boost the Ugly Betty's male viewership:

Sports Illustrated swimsuit model Brooklyn Decker will appear on an episode of the ABC hit this fall. The wife of tennis star Andy Rodick will appear as Betty's co-worker Lexie.

Not much else is known about the role, but Decker left the following post on her Twitter this week:

“Working on an amazing set!! Can’t tell you guys what it is... Just yet. But I can tell you.. I’m loving it and can’t wait to spill the beans!”

Sorry, Brooklyn. We spilled them for you.

Earlier this month, it was confirmed that Kristen Johnston was also coming aboard the show. She'll debut on the October 9 premiere.
