Los Angeles, Jul 2 (IANS): Singer Selena Gomez's daring dress with a thigh-high slit gaped open during a performance, sparking questions on whether she wore an underwear underneath or not.

It was a wardrobe malfunction of sorts when Gomez was performing at the AMP Radio Birthday Bash in Boston, reports thesun.co.uk.

The blunder happened as she bounded across the stage with her hand raised in the air.
She carried on a chunk of the show flaunting her pins, but at one point, she ended up exposing more than she had perhaps intended to.

Gomez was in a happy mood, and even turned her back on the crowd to show off her bare back to her fans. Her cheerful demeanour seemed to back reports that she’s not jealous about her ex-boyfriend Justin Bieber’s rumoured romance with Las Vegas waitress Jordan Ozuna.

"Selena has been doing a bunch of things like dealing with her mum and new sister, hanging out with friends and doing her own thing and really doesn't have time to worry about Justin anymore," said a source.

"She has seen how he has changed and doesn't want much of anything to do with him.
"As for the new girl, she doesn't even know who this new girl is, so she is not too worried about it. She has moved on and now she is happy Justin is moving on as well," added the source.
