Nick Lachey is NOT getting back together with Jessica Simpson.
As for Vanessa Minnillo, however, the singer has no comment about a possible reconciliation... because his tongue is too busy being tied around hers!
The couple - which broke off their three-year relationship in June - appeared quite frlendly at Dime bar in Los Angeles on Friday night, as witnesses told Radar Online:
"They were making out in one of the booths and seemed totally into one another. They were having a great time and definitely appear to be back on. They didn't care who saw them."
Nick and Vanessa reportedlty started going at it just 20 minutes after arriving at the club with friends. She was even spotted on his lap at one point.
Of course, the former couple has a long way to go until they reach the levels of PDA depicted in their July 2007 sex photos. Those are awesome!
