Paris Hilton and her ex Doug Reinhardt have reconciled, according to new reports.
The high-profile couple split at the beginning of the summer, but friends claim Hilton is the subject of recent Twitter.com posts from Reinhardt, in which he coos about his love life.
A source tells UsMagazine.com, "They are definitely happy again."
The couple started dating at the beginning of 2009 after Hilton split from Good Charlotte rocker Benji Madden.
Reinhardt recently posted a 'tweet' on Twitter, stating, "What an amazing weekend with my beautiful girlfriend. I love her so much!"
In a spring interview, Hilton declared she'd marry Reinhardt, explaining, "I'm really in love and really happy."
