Reports that newly single Jon Gosselin and tabloid reporter Kate Major are "just friends" seem increasingly dubious. The couple has been spotted vacationing together in the Hamptons for three days, Us Weekly reports. And tonight they're set to have dinner with Michael Lohan, father of LiLo, and Real Housewives' Jill Zarin. (Is the group preparing for a reality show face-off, Real World/Road Rules-style?) "He's a nice guy," Lohan Sr. said of the father of eight, who also recently vacationed with 22-year-old Hailey Glassman. Meanwhile, as Jon jet sets, Kate #1 has been watching over the kids in Pennsylvania.
