Have you been hysterically sobbing for two months since the tragic break-up of Paris Hilton and Doug Reinhardt? Well, cheer up person who doesn't exist because no one could possibly be that stupid, they're back together!

"They are definitely happy again," a source close to the couple -- who called it quits in June after four months of dating -- tells Us Magazine.

A rep for Reinhardt has no comment.

On Monday, Reinhardt, 23, posted on Twitter: "What an amazing weekend with my beautiful girlfriend. I love her so much!"

The day before that, he wrote: "Laying in bed watching SportsCenter with my girl."

Hilton, 28, declared she'd wed Reinhardt -- who dated Lauren Conrad on The Hills -- last April.

"He's going to be my husband," she told E! "We're best friends. It's not like we just met. We've known each other over the past year. I was in a relationship before and we reconnected. I'm really in love and really happy."

The reasonable person in me knows that Paris Hilton marrying anyone would be a terrible idea. On the other hand, the celebrity blogger in me knows that that Paris Hilton marrying anyone would be a hilarious idea! The boozing, the whoring, the partying, it all would be really sad/fantastic. I hope she thinks long-and-hard/rushes into this decision. I really don't/do want to see her make a stupid mistake, be heart-broken and wind up as a crack addict on the streets. Paris, please make good/life-destroying-awful decisions.
