We've already reported that these two have reunited in the past so this is nothing new to hear that they were seen in NYC at 5:30 am but here's the latest from Page Six:

HOLY hookups! Our favorite man-eating minx, Lindsay Lohan, was spotted at 5:30 a.m. yesterday coming back to the SoHo Grand hotel room of her ex-boyfriend, Wilmer Valderrama. The ex-couple had been partying together at Lotus into the wee hours Sunday night. Word is that Us Weekly has already bought pictures of the devilish duo leaving the hotel together. It was a full weekend for the "That '70s Show" party boy. On Saturday, Valderrama dined at Nobu with a posse of pals before letting off steam at Marquee and G-Spa.

I don't really care which guy she's hanging with these days - I just want her hangbag collection.
