The Sunday Telegraph reports

Things are heating up between Twilight hunk Kellan Lutz and his Aussie actor girlfriend Sharni Vinson.

The LA-based pair are expected to jet into Sydney to catch up with her family and attend the opening of The Star's Marquee nightclub tonight.

It will be Lutz's second visit here with Vinson, the last being over Christmas when they celebrated the festive season with her family in Cronulla.

"I've never seen Sharni happier," a friend said of Vinson, who played Cassie Turner on Home And Away for nearly four years before trying her luck in Tinseltown.

She and Lutz, famous for playing vampire Emmett Cullen in the Twilight series of films, have been together for almost a year.
