Brian McFadden has moved on from his split from Delta Goodrem by dating Irish model Vogue Williams, reports say.

The former boyband singer was spotted having a private dinner with Williams at a North Bondi restaurant last Thursday.

Williams jetted from Sydney to Melbourne last Friday with the singer, tweeting: "Having so much fun in Melbourne, australias deadly xx (sic)".

The Daily Star reports that the couple partied in some of the city's top venues, with McFadden introducing Williams to his star friends, including Dannii Minogue's partner Kris Smith.

'Fade Street' star Williams told Australian reporters: "It's great to catch up with Brian again. We met in Dublin about two months ago. I've been looking forward to coming to Melbourne."

Since splitting from McFadden last month, Goodrem has been romantically linked to singer Nick Jonas.
