AnnaLynne McCord sends out topless pic on Twitter

The celebrity naked Twitter photo bug has bit again. And its newest victim is none other than "90210" star AnnaLynne McCord.

The actress was sending a Tweet to one of her followers Jan. 5 when the slip up happened.

"This is for you. You rock! Xxx" she writes and includes the photo. But the photo revealed a little more than McCord may have wanted, an exposed left breast. Whoops!

McCord has since opted to crop the photo. But by that point, the one featuring the bare-breasted actress made the rounds on the web.

McCord isn't the first "90210" cast member to send out a topless photo on the Internet. Tori Spelling, who was a cast member in the original series "Beverly Hills: 90210," had her own run in when husband Dean McDermott sent out a picture of his uncovered wife in Nov. 2011.
