Ashlee was seen holding hands with her four-year-old son Bronx on November 28 in NYC, and Bronx was holding hands with an unidentified mystery man. Let's just say that this new guy is quite the hunk. You can check out a pic of him here to see for yourself.
Vincent and Ashlee had been dating for 19 months. Bronx's dad is rock star Pete Wentz.
"There was no bad blood and no third party involved," says a source. "It was honestly just a long distance relationship and it became too hard to make it work."
No word on whether this new guy makes Ashlee want to la-la.
