Ashlee Simpson took an early morning walk with Bronx yesterday in NYC, and it was Pete's turn to push the stroller for a father-son outing later on in the afternoon. Ashlee had only one of her boys with her to celebrate New Year's since Pete hosted a party in Las Vegas before quickly getting back to his family. Ashlee and Pete had to wait until he returned to share their 2010 celebratory kiss, while another member of the Simpson family was off partying away in a more tropical climate. Jessica was on vacation with friends, though no word whether she had her rumored flame Billy Corgan along for a special midnight smooch.
