Selena Gomez braved her first red carpet in the wake of her reported split from Justin Bieber on Monday.

The 20-year-old actress dazzled at Glamour’s Woman of the Year Awards at Carnegie Hall in New York City.

Selena wore a white peplum dress by Giambattista Valli with lace detail and a plunging neckline.

There was not a hint of sadness on her face as she posed for cameras on her way inside the event – hours after Justin tweeted a picture of himself at a recording studio.

The former Disney star, who is Glamour magazine’s December cover girl, didn’t comment on the break-up rumours.

E! News first reported the pair had called time on their two-year relationship on Friday.

Selena was said to have trust issues, and broke up with Justin a week prior to the report.

A source told the network their hectic schedules were also to blame.

Neither Justin nor Selena have confirmed the split.

The Baby hitmaker hinted there was trouble when he was asked about the rumours during an interview on America’s Open House Party radio show on Saturday.

"I don't know what to say," he shrugged, adding, "I don't know what's going on in my life. To even assess that, it doesn't make sense 'cause I have not made any comment.”
