Jessica Simpson swapped numbers with a Hollywood hunk during a recent party.

The singer-and-actress was at a cocktail party to celebrate Oscar-nominated movie ‘The Hurt Locker’ and soon caught the attention of one of its stars, Jeremy Renner.

Onlookers at the bash - which was held at the home of Madonna’s manager Guy Oseary - claim the pair couldn’t keep away from each other and hit it off immediately.

One told people.com: “Jeremy spent the night hitting on Jessica like crazy. They were really flirting up a storm.

“Jessica loved it! When the party was over, the two exchanged numbers, entering them into their phones.”

Jessica will welcome some fun into her life after ex-boyfriend John Mayer gave an interview in which he described their sex life as “crazy”.

Discussing his recent apology over the remarks, she told chat show host Oprah Winfrey: “I haven’t written back. I don’t accept it… I hope he gets his life together.”
