This past Sunday (Mar 13), Charlie Sheen‘s 2-year old twin sons, Bob & Max, celebrated their second birthday with a lavish backyard celebration attended by celebrity guests includinf David Katzenberg, Nicky Hilton, and Adrienne Maloof. The party was literally filled with celebrity A-listers, but somehow failed to invite the biggest star of them all….Charlie Sheen!

Sheen’s soon-to-be ex wife, Brooke Mueller, enlisted the services of Kathy Hilton (mother of socialite Paris Hilton) to host Bob and Max’s party at the Hilton family home in Bel Air, CA. And while their father was noticeably absent, an eyewitness tells UsMagazine.com the birthday boys seemed to be having a “great time”.

“Max and Bob were in heaven running around and sliding down the slide of the bounce house,” the witness tells Us of the boys’ big day. “They got a ton of presents including tee ball sets and race cars.”

Although the twins were the ones showered with lavish gifts, it seems that in actuality Mueller was the one who received the best gift of them all: peace.

“Brooke seemed to have a good time too and was relaxed and happy. She seemed focused on her kids and nothing else,” adds the insider. “There was a lot of security outside at all times to make sure no uninvited guests got in. There was no sign of Charlie at the party.”

Only two years old, and already these tiny tots are securing A-Listers and lavish gifts for their fabulous birthday blowouts. Yup…pretty sure it’s safe to say that these two tiny warlocks are already “winning” in life.

Happy birthday guys!
