Angelina - who is currently shooting upcoming movie, Salt - is said to eager to add two more kids to her already six-strong clan.

A source tells the Mirror, "Angelina is absolutely loving the joys of motherhood and is keen to expand her family this year."

"At the moment she is renting a house in Long Island while shooting Salt. As soon as that's over she is planning to fly abroad to find a new baby.

"When that is all sorted she has discussed finding somewhere new and interesting to live to start trying for a fourth natural baby. She is very keen to get pregnant again."

Meanwhile, Angie might want to ditch the liquid detox diet before she attempts to conceive if rumours that her increasingly frail appearance is causing concern on set are to be believed.
