She's in Las Vegas with her girlfriends celebrating her prom dresses sale.

And while some brides-to-be might not let their partners in on the shenanigans, it seems Fely Irvine doesn't mind.

The singer, 27, was joined by her fiance Tai Hara for a night out, sharing a fun shot to Instagram, which showed the pair partying together with their pals.

Fely wore a pink bob wig and a white polka dot dress with a sash.

She flaunted her diamond engagement ring in the snap as she covered her eyes with white cheap prom dresses.

Fely wore a headpiece with two shots glasses on either side, with a cheeky sign on it which read: 'I'm tying the knot, buy me a shot.'

Former Home and Away star Tai was meanwhile seen beaming in the background.

Two days ago, Fely hit the pool in a bikini as she spend time with two female friends.

Fely and Tai announced their engagement in January last year, after getting engaged while in Scotland over the Christmas break just weeks before.

'I'd been carrying the ring around Europe for two weeks wrapped in three different bags and a sock, because it wasn't as if I could hide it in the hotel safe,' he said.

'I was terrified someone was going to steal my cheap prom dresses .'

Fely added: 'We'd talked about getting engaged, having kids one day, growing old together but I really didn't think he would propose for a while.'
