Nick Lachey is back together with girlfriend Vanessa Minnillo after splitting in June. “I was single for a minute there, and then we’ve kind of patched things up there,” Lachey confirmed while visiting Good Day Philadelphia.

But the reunion could be short-lived if Lachey doesn’t get around to popping the question, according to Star magazine.

“She never stopped loving him when they were apart,” a source says. “But she doesn’t want to waste time if he has no interest in marrying her.”
