ET has a sneak peek at tomorrow night's episode of "Ugly Betty," on which Betty (AMERICA FERRERA) decides that it would be better to befriend her rival Charlie (guest star JAYMA MAYS), who is pregnant with Betty's boyfriend's baby.

So Betty, who has her romantic dinner with Henry (CHRISTOPHER GORHAM) interrupted by an interfering Charlie, decides to keep her enemy closer by throwing her a baby shower. It turns out to be an unforgettable bash!

Also on Thursday night's episode, airing at 8 p.m. on ABC, EDDIE CIBRIAN begins a multi-episode storyline as Coach Diaz -- Justin's (MARK INDELICATO) coach -- and a possible love interest for Hilda (ANA ORTIZ).

Then Christina (ASHLEY JENSEN) learns just whose baby it is that Wilhelmina (VANESSA WILLIAMS) has blackmailed her into carrying; and Daniel (ERIC MABIUS) falls apart after his disastrous last encounter with Wilhelmina's sister Renee (GABRIELLE UNION) in which she set his apartment on fire.
