London: 'Mission Impossible 4' star Paula Patton says she is convinced her son is a good luck charm because she landed a coveted role in the film months after he was born.

The actress, who is married to singer Robin Thicke played the part of Jane opposite Tom Cruise in 'Mission Impossible: Ghost Protocol' just five months after delivering son Julian Fuego,  a leading daily reported.

She had conceived the boy during awards season, when her 2009 movie 'Precious' based on the novel 'Push' by Sapphire was taking home many top honors and she's adamant her baby brings her good fortune.

"I was pregnant during the whole awards season of Precious and then I gave birth to my son. Five months later I got the role, so he's been my good luck charm, my little boy," she said.
