She’s already suffered an underwear malfunction this week after stepping out minus her bra.

And today teen singer Miley Cyrus had another wardrobe mishap, wearing a skin-tight floral minidress that was too tight to zip up at the back.

However the 17-year-old star seemed unbothered by her ill-fitting outfit as she chatted to photographers near her home in the Los Angeles suburb of Toluca Lake.

She confirmed she’s still dating on-off actor boyfriend Liam Hemsworth, but that he is away for the next two weeks.

Yesterday she also looked very relaxed as she headed to a casual family lunch.

The see-through top showed that the teenager had gone bra-less for the day as she met her mother Tish and little sister Noah to eat.

And she seemed oblivious to the stares she was attracting as she walked towards Patty’s diner in Toluca Lake.

Maybe she thought it was a cool look on Britney Spears, who is often snapped out and about without a bra on.

Miley teamed the shorts and slashed T-shirt with a aquamarine pendant and short brown suede moccasin boots.
