Pitt celebrated Aniston's birthday after split

Splitting from husband Brad Pitt didn't stop former Friends star Jennifer Aniston from partying with friends, or Pitt himself.

The Good Girl star Aniston and the Ocean's Twelve actor Pitt, 41, who had announced their split Jan 7, had invited about 80 friends to their Beverly Hills home to celebrate Aniston's 36th birthday last Saturday, reported the People magazine.

"It was a lovely party," one of the friends was quoted as saying. The couple "were very friendly to each other".

"She had presents delivered to her the whole week (prior to February 11, her actual birthday). She got amazing gifts," another friend said.
