Happy 25th, AnnaLynne McCord!

The 90210 beauty is celebrating a big birthday on Monday, and in honor of her special day, Breaking Celebrity News has photos of her showing off her bombshell bikini body.

Getting recognition on the hit show Nip/Tuck, it was the remake of the Beverly Hills 90210 that really thrust the gorgeous young star into the public eye.

After a high-profile romance with Kellan Lutz, AnnaLynne found happiness in the arms of an older man. She has been dating Prison Break star Dominic Purcell -- 17 years her senior -- for more than a year.
