After parting ways with her boyfriend, Brahim Zaibat, pop star Madonna is reportedly planning to celebrate Christmas with her ex-husband Sean Penn.

The 55-year-old went on a charity trip to Haiti with Penn, and it is said that the former couple might reconcile.

Contactmusic.com reports that a source told The Sun newspaper that "she needs someone who is more of an equal. She needs to be challenged, which Sean does."

"Sean and Madonna now want to see each other over Christmas and Madonna's even considering getting a place out in Haiti. They're in touch non-stop. Friends are joking they'll be remarried by this time next year," the source added.

Madonna was reportedly urged to end her three-year-old romance with Zaibat, 25, at the Kabbalah Centre here.
