EXCLUSIVE VIDEO & INTERVIEW: Jon Gosselin: Rocket Man By Day, Bar Fly At Night

After a few days in New York with girlfriend Hailey Glassman, Jon Gosselin returned to reality – reality TV that is. In this RadarOnline.com exclusive video you can watch Jon launch a water-propelled rocket while TLC cameras filmed it all for Jon & Kate Plus 8.

Meanwhile, wife Kate delivered a rocket of her own on Monday, taking on Jon, her brother, rumors of her infidelity with her bodyguard, and Jon’s relationship with Hailey. Kate let loose in a two-segment Today Show interview that left few survivors.

The video of Jon was shot Saturday at his Pennsylvania house. After launching the rocket he talked to RadarOnlne.com about hanging out with the kids and how much he had missed them the past few days. And once kid time was over, Jon returned to his favorite night spot, Legends, and hung out until the early morning hours, an eyewitness told RadarOnline.com exclusively.
