The 27-year-old actress – who has recently been romantically linked to Bradley Cooper – tweeted a picture of her pet pooch, admitting he is the only man she has been spending time in bed with recently.
Writing on her twitter page, she said: “Ok I know I'm not supposed to tweet sexy photos (damn you [Anthony] Wiener! But here is my and my (only!) boyfriend in bed.(sic)”
Earlier this weekend, the ‘Tron: Legacy’ star explained she found speculation about her love life “funny” because her dog is the “only one” she needs.
She told People.com: “It is funny, actually. I have to laugh. I'm not dating anyone. He is my only boyfriend. He's the only one that I need."
This comes after an onlooker at a recent bash at New York’s Boom Boom Room confirmed Olivia - who was recently romantically linked with Justin Timberlake following her split from husband Tao Ruspoli – was “definitely” Bradley’s date.
The insider said: “Olivia was Bradley's date. He was always taking her hand or putting his hand on her lower back, it was really sweet. He took care of her all night. They were definitely together.”
