Following a wardrobe malfunction at the Tom Ford Fashion Show in Los Angeles last week, American singer Beyonce carefully managed to avoid another such episode when she stepped out for lunch with husband Jay Z at Gracias Madre in West Hollywood.

The 33-year-old wore a short denim skirt and a completely unbuttoned light blue shirt. Although she narrowly missed a wardrobe malfunction, her bra-less outfit turned many heads.

The cleavage of "Mrs Carter" was clearly visible through the tied-up top, reported Daily Mail.

Last week, Beyonce reportedly became a victim of wardrobe malfunction during the Tom Ford Fashion Show in Los Angeles.

"Beyonce had a huge wardrobe malfunction at the show. Her dress ripped all the way up the back and she had to run backstage to find something else to wear," a source told US Weekly.

The insider also revealed that the "Single Ladies" singer was really embarrassed and had to cancel her show since no one could fix her outfit in time.
