New Delhi (ANI): Hollywood actor Brad Pitt has reportedly given his lover Angelina Jolie the biggest ultimatum ever — either marry him or forget him. The Gia actress, who is keen to have more kids with Pitt, has been told by him that he will not have anymore kids with her unless she ties the knot with him, reports the China Daily.

"Brad's told her, ''Marry me, or it''s over.'' He definitely wants to get married before they have any more babies," a source told Brit magazine OK! Pitt is said to be worried that Angelina is spending very little time with him and her kids due to her work. He has even moved to New York''s Waldorf Astoria hotel with his six children to be closer to Jolie, who is filming new spy flick ''Salt'' there.

"Their relationship is so out of kilter, he believes marriage is the only thing that will bring it back around," the source said. "He needs to know Angelina is really committed to him. Becoming Mrs. Pitt would give him that answer," the source added. What"s more is that Pitt was left fuming when after he suggested Angelina to attend couples'' counseling to save their relationship, she asked her ex-husband Billy Bob Thornton for his opinion.

"This just caused more friction with Brad because although he doesn't have a problem with her talking to her exes, he doesn't understand why she would take Billy Bob''s advice to try therapy as when he suggested it to her she reacted very angrily," a source told Brit magazine Grazia.
