The pair were reportedly spotted flirting at Voyeur in El Lay, and then later "making out" at actor Shawn Pyfrom's house party!
"There's always been an attraction between them. [But] Lauren is just enjoying herself. She's not taking anything too seriously!"
We wouldn't be opposed to 'not taking anything too seriously' with Nate Archibald, ourselves! Ha!
Get it, gurl!
