Angelina Jolie has reportedly turned downed Brad Pitt's marriage proposal. The stunning Tomb Raider actress, who is heavily pregnant with the actor's baby is refusing to walk down the aisle. A source revealed to Grazia magazine: "Brad has literally got down on his knees to beg Angelina to change her mind but she laughs pulls him to his feet, kisses him and says, 'Let's not ruin something so perfect'."

However, Brad's traditional parents are apparently unimpressed with their son fathering up a child out of wed-lock. The source added: "They'd rather their son bring a child into the world with the benefit of marriage."

Angelina is reportedly anxious not to rush into another marriage following her divorces from actors Jonny Lee Miller and Billy Bob Thornton.

The couple are currently in Namibia with adopted children Maddox, four, and one-year-old Zahara awaiting the birth of their first child together.
