Radio star Fifi Box upstages the bride as she attends her friend’s wedding in a VERY low cut dress

Radio star Fifi Box left little to the imagination as she attended a wedding this weekend.

The 46-year-old presenter showed off the flesh in a low-cut dress as she celebrated her friend’s special day.

Fifi put on a busty display, showing off her tiny waist in a revealing dress with a plunging neckline and cutout at the front.

She posed next to the bride, who wore a long tulle dress with a sheer neckline and layered sleeves.

‘This is the perfect bride. She is the perfect friend who gets her perfect fairy tale with Ben and her beautiful bubba Finn. There was so much love on this day,” Fifi wrote.

It comes after Fifi recently revealed she is ‘officially off the market’ and is in a new relationship with Rocky, one of the dads at her daughter’s school.

The radio host and media personality excitedly shared the happy news on her Fox 101.9 radio show Fifi, Fev and Nick in August.

Fifi, whose last public relationship was with former Ironman Grant Kenny, told listeners: ‘I’ve got some news. I’m in a relationship! I’m not single anymore!’

Fifi admitted his name was Rocky, but she called him “hot dad” to her friends.

The mother-of-two revealed they met during the school run in Melbourne after repeatedly making eye contact.

She said they never really got to talk until her daughter Daisy, now four, had a breakdown on the playground and it helped the couple break the ice.

‘I don’t fall in love often, but a man piqued my interest. And he was one of the guys who picked up the school. We called him a handsome dad,” Fifi explained.

‘I was able to determine that he is a single father. I didn’t know how to talk to him. I owe that to my daughter Daisy.

She threw the mother of all tantrums, she hadn’t slept, she turned it on,” Fifi said laughing.

“I think I was dragging her around the playground because I thought it was so embarrassing, and I looked up at him and he was laughing his head off,” she said.

She sweetly added, “I’m officially off the market!”
