Shane Warne's ex-wife Simone Callahan flaunts her new lover

It looks like Shane Warne's ex-wife, Simone Callahan, has left her past behind. She has stepped out publicly for the first time with new love Toby Roberts.

The glowing couple paraded their romance, arriving hand in hand at the Myer autumn/winter fashion launch in Melbourne.

"Everything is good ... it is our first date," the Herald Sun quoted Callahan as saying.

It may be their first public outing, but a beaming Callahan said she had been seeing Roberts for six weeks.

Callahan first clapped eyes on the handsome part-time model when he was up a ladder doing some handyman work at a mutual friend's home.

Roberts was a little startled at the attention he and Callahan generated on their arrival.

"It is OK, I am taking it all in my stride," he said.

Of his relationship with Callahan he said: "We take it a day at a time."
