Simon Cowell takes Mezhgan Hussainy out for lunch with his mum

Music mogul Simon Cowell recently took Mezhgan Hussainy out for lunch in LA with his mum Julie Brett and a pal.

The ladies got on very well and even shared a giggle as Hussainy, 37, tweaked Cowell, 50, on the chin at the table at seafood grill McCormick & Schmick.

And they all had a good laugh when a tourist stopped Cowell in the street... to ask him to take a picture of them.

"They didn't seem to have a clue who he was," the Mirror quoted an onlooker as saying.

"They were oblivious to the photographers who were taking his picture. Simon saw the funny side. It made a change," the onlooker added.
