The actress dodges various dating rumors by joking that her pet is the main man in her life

Olivia Wilde has made headlines lately for being spotted with a string of eligible A-list bachelors.

But the actress, 27, took to Twitter once again, denying that she and any of these famous rumored flames are relationship bound.

“Ok I know I’m not supposed to tweet sexy photos (damn you [Anthony] Wiener! [sic]),” she wrote on Friday. “But here is my and my (only!) boyfriend in bed.” PHOTOS: All the Single Ladies – with Dogs!

But Wilde’s Twitter followers shouldn t think this means that the typically private actress has suddenly decided to reveal something personal. The picture is in fact of her dog, who apparently makes for a cute cuddle partner.

The Tweet comes fresh off the heels of Internet speculation that recently divorced Wilde is romantically involved with Bradley Cooper. In April, the House, M.D. starlet also Tweeted that despite rumors, she isn’t dating Justin Timberlake.

On Saturday, at the Chrysalis Butterfly Ball in L.A., the actress said she finds speculation about her dating life amusing. “It is funny, actually,” she told PEOPLE. “I have to laugh. I’m not dating anyone.”

Still, there’s always her pooch. “He is my only boyfriend,” she said, laughing. “He’s the only one that I need.”
