Actress Paula Patton squeezed herself into a bra one size too small for two years after becoming a first-time mother to give herself a natural breast lift.

The Mission: Impossible - Ghost Protocol beauty welcomed her first kid with her singer husband Robin Thicke in 2010 and she admits it was a key piece of advice from her mum which helped the star avoid developing saggy boobs following childbirth.

She tells U.S. breakfast show Today, "Once I finished breastfeeding, my mum's like, 'Don't take that bra off ever!' Mum, thank you.

"I wore a one-size-too-small bra for like, two years. It helps...! They don't fall, you teach them, you teach them to come back!"

Patton showed off her enviable curves on Monday night (29Jul13) when she walked the red carpet wearing a figure-hugging dress with a plunging neckline at the Los Angeles premiere of her new film 2 Guns.
