Chyler Leigh Chyler Leigh

Looks like "Little Grey" is having another little one of her own.

Chyler Leigh, who plays Meredith's (Ellen Pompeo) half-sister Lexie on ABC's Grey's Anatomy, is pregnant, her reps confirm to

No word yet on gender or due date, but the new addition will be the 26-year-old actress' third child with actor/musician hubby Nathan West.

An ABC insider tells that there are no plans to write Leigh's pregnancy into Lexie's storyline. (Sorry, Mark!)

Leigh's other credits include the short-lived series Reunion and That '80s Show, as well as Not Another Teen Movie.

Do you think Leigh's pregnancy should be written into Grey's, or should the producers stick with strategic camera angles as a work-around?
