The Hills are alive… with the sound of more reunion rumblings!

Heidi Montag just hinted that the MTV hit’s stars could possibly get back together onscreen for the first time since the reality series’ sad end in 2010.

“I had the funniest dream Lauren Conrad, Audrina Patridge, Whitney Port and I were performing like the Spice Girls for our Hills Reunion!” the 27-year-old blonde Tweeted on April 23. 

Sure the pop performance was a dream, but could the reunion be real?

According to a source close to Lauren Conrad, 28, it’s all just in onetime nemesis Heidi’s head.

“As far as I know, that’s not true at all,” the insider says of plans for an upcoming reunion.

But fans shouldn’t give up all hope— season six star Kristin Cavallari, 27, recently said she would be on board for a cast gathering. “I would love to do it,” the expectant mother of Camden, 1, told E! News. “I think it would be a ton of fun to catch up with everybody."
