'Betty's been making headlines lately: LiLo's guest starring in the May 22 season finale and the entire show, which is set in New York but shot in L.A., is considering moving production to the Big Apple. (Side note: Wouldn't an 'Ugly Betty'/'Gossip Girl' crossover be hilarious? Completely impossible, but fun to think about.)

Back to 'Betty'... last week's second new episode back from the strike had a very fierce guest star: Christian Siriano, winner of 'Project Runway' (you can just imagine what he said to Alexis).

While Christian hammed it up, Daniel's wacko girlfriend Renee got crazy jealous of Betty -- and Daniel even thought Betty might have feelings for him. Hilda's nemesis, Gina Gambarro, returned married and rich, while Henry confronted Gio about his feelings for Betty.

Last night, 'Project Runway's' Christian Siriano made his prime-time comedic debut on the hit show 'Ugly Betty'. The 22-year-old winner of must-see Bravo series made a cameo as an exaggerated version of himself alongside 'Runway' judge Nina Garcia. We all know Christian has a flare for drama, so it's hard to tell if he's really acting at all in this clip. You be the judge.
