Mashup in the making? Britney Spears good-humoredly replied back to a fan who tweeted a hilarious photo comparing her airline stewardess hat in her hit "Toxic" music video to Russell Crowe's hefty blue headpiece in Les Miserables.

"Hey @britneyspears did you see @russellcrowe in #lesMis maybe he is fan of you," the excited fan wrote to the 31-year-old singer.

Spears replied back gamely, tweeting at Crowe: "You wear it well. Maybe we should perform a Toxic/Work Song mashup."

In Spears' 2004 video, she plays an international spy who takes on multiple aliases, including an air stewardess vixen with a jauntily-worn blue cap.

Crowe, 48, plays Javert in the Oscar-nominated film, a prison guard and policeman who acts as Hugh Jackman's Jean Valjean’s main nemesis.

The lighthearted exchange comes amid Spears' much-publicized split from fiance Jason Trawick. The pair pulled the plug on their engagement earlier this month though both insist the decision was an amicable one.

"Jason and I have decided to call off our engagement," the singer told Us Weekly in a statement Friday, Jan. 11. "I'll always adore him and we will remain great friends."

Spears reportedly returned the $90,000 engagement ring to Trawick shortly after their public announcement, and Trawick, 41, had his name removed from her conservatorship.
