Bradley Cooper and Renee Zellweger Break Up

Bradley Cooper and Renee Zellweger Break Up

Zellweger, party of one.

Newly single Renee Zellweger, fresh from her breakup with Limitless star Bradley Cooper, was seen dining alone at a restaurant in New York City. She was spotted chatting away on her cell phone with headphones in both ears. She smiled and didn't look too upset up about the breakup.

But the split caught most people by surprise, coming just days after Cooper hailed her from the stage as he appeared on The Actors Studio.

Even Cooper's mother beamed as she sat by Zellweger's side.

While she was out and about in New York, Zellweger also stopped into a local bookstore. She bought a book called The Social Animal: The Hidden Sources of Love, Character, and Achievement.

Meanwhile, with Limitless # 1 at the weekend box office, Bradley Cooper was 3,000 miles away, arriving at Los Angeles International Airport. He also managed a smile.

So why did the couple split? Gawker.com says it was because Cooper wouldn't pop the question.

When he appeared on Howard Stern's radio show recently, he had this to say on the subject.

"Is she your fianceé?" asked Stern.

"No," said Cooper.

"What planet am I on? I thought she was your girlfriend," said Stern.

"Yeah, but fianceé and girlfriend are two different things," said Cooper.

"Oh, so you never asked her to marry you?" asked Stern.

Cooper replied, "No."

No wonder Zellweger is dining alone.
