Rumors of a Kristen Stewart and Robert Pattinson reconciliation have been swirling the past week, but now sources are saying not only are they back on, but they've moved back in.

According to an Us weekly insider, "They are living together and have reconciled."

The mag reported last week that the "Twilight" couple had a "dramatic makeup" after months apart. In July, Kristen, 22, was photographed getting really friendly with her "Snow White and the Huntsman" director, Rupert Sanders, 41, and quickly admitted having an affair.

Both Kristen and Rob kept quiet about their breakup, but one at a time, they were spotted moving out of the L.A.-area house they shared.

But now, the pair seem to be back to being a couple, just in time to go on the road and promote their latest "Twilight" flick.

"Rob sees it as Kristen made a really stupid mistake," a source told UK newspaper the Sun. "After a lot of long tearful talks, they've worked it out."

Let the Twihards rejoice!

Interesting pairings

One of two new couples who have caught our eye this week are Simon Cowell and Carmen Electra.

The duo were spotted on a dinner date over the weekend in West Hollywood. One nosy diner said Simon, 53, and Carmen, 40, were leaning in, talking close and soon started making out.

The pair has reportedly been flirty with one another before when the "Scary Movie" actress guest-judged on "Britain's Got Talent" in February.

The other couple: Seth MacFarlane and Emilia Clarke.

Seth, 38, who is known for his plethora of voices, was spotted wrapped in the arms of the "Game of Thrones" star, 25, this week.

Emilia (known as the mother of dragons to her "GOT" fans) was first seen with the funnyman at the HBO Emmys afterparty on Sunday.

But according to an Us source, "It's been going on for a few months."
