Talk about a busy week for the Kardashian family! Just a day after sister Khloe tied the knot with L.A. Lakers player Lamar Odom, big sister Kim Kardashian officially reconciled with her NFL running back beau, Reggie Bush.

"They're totally back together for real," says a source close to the couple. "Kim and Reggie spent a few months apart getting their priorities together and figuring out who they were as individuals so they can make it work together."

The pair are so close that Bush's parents even attended Khloe's weekend wedding, the source adds.

Says another pal: "They are still very much in love."

Kardashian, 28, and Bush, 24, amicably split in July. They were spotted together in New Orleans just three weeks later, but did not reconcile at the time.
