Renee Zellweger's flirty date

Renee Zellweger has enjoyed a romantic meal with Jennifer Aniston's rumoured boyfriend.

The Oscar-winning actress and Bradley Cooper - who reportedly began dating the former 'Friends' star last month - were seen flirting during dinner at exclusive New York restaurant Antonucci.

An onlooker told America's OK! magazine: "He pulled her chair out for her when she sat down and he kissed her on the hand. If they're just friends, they were being awfully affectionate!

"Throughout the dinner they were playful and flirty. She played with her hair a lot, and she would often touch his arm when she was making a point about something.

"At one point, he seemed to want to whisper something to her as if it were a secret. He spoke into her ear and then they both started giggling."

Renee surprised her dinner companion by secretly paying the bill before he had a chance to.

The source added: "She told him she wanted to buy him dinner to pay him back for something. And when he opened the bill, it already had her card in it!"

Last month, it was claimed Jennifer was taking her relationship with Bradley slowly after many of her previous relationships ended badly.

A source said: "They're both sticking their toes in the water. She's moving at a snail's pace about all this. It's not a romance yet, but they are interested in each other."
