Adriana Lima made her first appearance on the set of Ugly Betty

It looks like Lindsay Lohan isn't the only celebrity guest star on the new season of "Ugly Betty." Yesterday (September 9), Adriana Lima was spotted on the set, making her acting debut.

The Brazilian beauty looked stunning in a strapless purple and grey gown as she posed for stills on location in New York City's Central Park as part of her "Ugly Betty" gig.

And her rep, Liza Anderson, recently told press that landing the guest spot is a dream come true for Lima. "Adriana has always been a huge fan of Ugly Betty and is thrilled for the opportunity to make a guest star appearance."

Appropriately enough, Adriana (playing herself) will be hired to pose on the pages of Mode's "sizzling hot issue" and work with the title character on a cover story about the virtues of the made-up "tico berry" for beauty.
