Brad Pitt has demanded Angelina Jolie marry him.
The 45-year-old actor - who has been dating Angelina since 2005 and raises six children with her - has reportedly told twice-divorced Angelina he will not have any more children with her unless she agrees to tie the knot.
A source told America's OK! magazine: "Brad's told her, 'Marry me, or it's over.' He definitely wants to get married before they have any more babies."
Brad - who was previously married to Jennifer Aniston - is said to be feeling increasingly frustrated with the lack of time he is spending with Angelina, 33.
He is currently staying in New York's Waldorf Astoria hotel with the children to be closer to Angelina, who is filming new spy movie 'Salt' in the city.
The source added: "Their relationship is so out of kilter, he believes marriage is the only thing that will bring it back around.
"He needs to know Angelina is really committed to him. Becoming Mrs. Pitt would give him that answer."
It was recently reported Brad had pleaded with Angelina to attend couples' counselling in a desperate bid to save their relationship.
Angelina is said to have agreed, but only after seeking the advice of her ex-husband Billy Bob Thornton.
A source told Britain's Grazia magazine: "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."
