Heidi Klum and her kids: Leni, 8; Henry, 7, Johan, 6; and Lou, 3, took advantage of New York City's gorgeous weather today with a trip to a Soho playground. After working up a sweat on the monkey bars, the kids were treated to some frozen yogurt at Pinkberry. Sounds like a nice afternoon to us!

Heidi and her estranged husband, Seal, have been seen out and about NYC with their kids very often lately, often dropping them off and picking them up from visits. The couple stunned Hollywood in January when they announced that they would be separating. The Project Runway host officially filed for divorce in April.

Yesterday, Heidi Tweeted that her broken toe (she injured it at Leni's birthday party in May) was fully healed. "No more broken toe!" she wrote. "Back to running!" Along with the message, she Tweeted a photo of her triumphant return to form.

Looks like Heidi's getting back to fun, also.
