Now batting for Jeter

Derek who?

Minka Kelly and Hollywood heartthrob Wilmer Valderrama have made no secret of their newly minted mutual affection while on vacation in Australia.

The former flame of Yankee stud Derek Jeter and “That ’70s Show” star Valderrama — who’s been romantically linked to a long list of stars ranging from Rihanna to Lindsay Lohan — strolled like lovers in Sydney along the city’s picturesque waterfront.

Valderrama even posted a picture of the couple with friends on his Twitter account yesterday.

“Homies & Homiettes boat cruising in #Sydney,” he wrote of what appeared to be a cellphone self-portrait.

Kelly, 31, and Valderrama, 32, have been “acting like a couple,” sources said, and were photographed holding hands last Friday.
