Making the rounds to promote their respective projects, Nina Dobrev and Katherine Heigl stopped by "Extra" in Los Angeles on Friday (January 10).

The "Vampire Diaries" star showed off her gorgeous gams in a black miniskirt with a white blouse and black blazer while the "Knocked Up" actress looked chic in a white top, black pants, and a black jacket.

During her appearance, host Mario Lopez surprised Nina with a cupcake to celebrate her 25th birthday.

It's an exciting time for the actress as she just nabbed a People's Choice Award for Best Onscreen Chemistry with co-star (and ex-boyfriend) Ian Somerhalder.
