Jude Law’s kids — Rafferty, 10, Iris, 6, and Rudy, 4 — go climbing up tree in a London park on Thursday while mommy Sadie Frost (and Jude’s ex-wife) chatted away with a gal pal.

Jude is currently vacationing in India with his new lady love, Kim Hersov, editor-at-large for Britain’s Harper’s Bazaar.

JJ Note: Looking at the pictures more closely, I don’t think Rudy or Iris are pictured here but that’s definitely Raf.

Jude Law took his ex-wife Sadie Frost and their 6-year-old daughter Iris to South Africa this past Tuesday to make Christmas extra special for a group of children at the KwaZulu-Natal orphanage.

“Our children are wrapped up in the material world,” said Jude. “It is important to go to this place and see how lucky they are. As a family it’s an amazing thing to do.”

Jude, 33, directed a traditional play while Sadie, 41, joined in the tribal dance celebrations. You can also see Jude’s wild reaction after tasting a ceremonial drink. Must have been really, really bitter/sour!!!

The event was held at God’s Golden Acre at Cato Ridge near Pietermaritzburg. God’s Golden Acre is a non-profit charity involved in the care of children who have been orphaned, abandoned, or devasted by HIV/AIDS in Kwa-Zulu Natal, South Africa.

Heather Reynolds, the founder and spokesperson for God’s Golden Acre, commented: “We’ve had visits from Oprah Winfrey and Sadie Frost before. Oprah had a great time with the children and she was so touched by their friendliness. She had fun chatting to them and getting to know them better. Sadie also enjoyed her last visit, which is probably why she wants to come back with Jude and the children… I think people like coming here because we respect their privacy and it’s a serene place where they can just relax and be themselves. The children are great and just give them such a warm reception. It’s really a place where anyone can feel at home with the children and we can be one happy family.” More pictures after the jump…
