It's been only a week since Zac Efron reclaimed his single status after his four-year romance with Vanessa Hudgens fizzled out, but the rumor mill can't wait to push him back into the dating pool.

For right now at least, the dreamy-eyed, nonthreatening star, 23, remains in the shallow end, with E! Online reporting that he's been getting "chummy" with Taylor Schilling, his co-star in the currently filming romantic drama "The Lucky One."

Sources claim Zac is "leaning" on the 26-year-old actress as he works through the split, although nothing romantic is said to be happening at the moment.

"They joke around, eat together sometimes, run lines," relays an insider. "Nothing out of the ordinary."

But given how often co-stars hook up, E! wonders whether being "good friends" could soon lead to something more.

In response to the romance rumblings, Efron's rep tells Wonderwall, "They worked on a movie together. That's all."

Following the actor's parting of ways with Hudgens, a spy told Us Weekly that he was eager to sow an oat or two.

"He wants to put his whole 'High School Musical' past behind him and be known as a sexy solo actor like Leonardo DiCaprio," said the source. "He was ready to experience life as a single man."

When asked about Zac, Vanessa gave reporters a thumbs-up and responded, "We're good."
