Lachey, Minnillo 'spotted making out'

Nick Lachey and Vanessa Minnillo have sparked speculation that they have rekindled their romance after being spotted together in three different cities in one week.

The couple, who met on the set of Lachey's video for 'What's Left Of Me', had confirmed that they were separating in June following a three-year romance.

However, sources have told People that the pair were spotted "making out" in Los Angeles last weekend, before partying together on the East Coast on Wednesday and in Cincinnati the next day.

"Nick and Vanessa are not officially back together, but they're hanging out," said a friend of the couple.

"They'll see what happens. Maybe a reconciliation will happen, but they're not exclusive right now."

Friends and family of Lachey recently denied reports that he would reunite with ex-wife Jessica Simpson, who ended her romance with Tony Romo in July.
