Chris Martin and Daughter Apple: Whee!

Chris Martin, 31, currently a little stressed by both a copyright lawsuit and rumors that his marriage to wife Gwyneth Paltrow, 36, is on the rocks, enjoyed some downtime with his daughter Apple, 4, at London’s Hyde Park’s Winter Wonderland.

Martin, bundled up in a down jacket against the cold, went for a slippery slide with his and Gwyneth’s eldest child.

Martin’s band Coldplay has been accused in a recently filed lawsuit by virtuoso guitarist Joe Satriani of ripping off his 2004 song “If I Could Fly” for their Grammy-nominated hit single “Viva La Vida.”

Tongues are wagging that Chris and Gwyneth’s marriage is hurting. A recent report in the New York Daily News had Gwyneth following in BFF Madonna’s footsteps by filing for divorce.

Paltrow was recently linked with billionaire Jeff Soffer, 41, and was said to have spent Thanksgiving at his Indian Creek Island mansion in Florida.

“Gwyneth has confided to friends she and Chris are taking a break,” a source said. “Jeff is crazy about her.”

Sounds like Martin could use a few more trips down that slide.
