Pamela Anderson has celebrated her 40th birthday with ex-husband Tommy Lee.
The former 'Baywatch' actress and Tommy partied at the Planet Hollywood Hotel on Saturday night (30.06.07), until 6am the next morning.
One partygoer said: "She was having a ball. You would never guess she's 40."
The birthday celebrations began on Thursday (28.06.07) when Pamela arrived at the Planet Hollywood hotel with her parents and two sons 10-year-old Brandon and nine-year-old Dylan.
The boys later watched their mother perform as a magician's assistant alongside Hans Klok in his stage show 'The Beauty of Magic'.
After Saturday's show the actress was presented with a cake saying "Happy birthday Pamela" and Klok gave her an autographed copy of Harry Houdini's only book, written in 1920.
A source said: "She made Tommy and photographer David LaChapelle touch Houdini's autograph for luck and magic."
At the private party Pamela and Tommy, 44, appeared to be reigniting their passion for each other.
A source said: "They were definitely close to each other, cuddling and being quite affectionate. They clearly love each other and have tremendous passion for each other."
On Sunday morning Pamela retired to a bedroom filled with Pink balloons and matching flowers. |
