When you're 86 and a gorgeous 26-year-old blonde is begging you to take her back, you can probably forgive stuff like the time she called off your wedding just five days ahead of time, found herself another man and said you were bad in bed. Water under the bridge!

According to RadarOnline, Crystal Harris and Hugh Hefner are back together and she has returned to the Playboy Mansion.

"Crystal begged Hef to let her come back," a source told "He surprisingly doesn't have any hard feelings against her, so he let her move back into the Mansion."

But maybe Hef's other special lady friend does have hard feelings against both of them. "Shera Berchard, Hef's #1 girlfriend, moved out as soon as Crystal moved back in," the source said.

Maybe Crystal and Shera can run away together next time. Head here for a pic of Hugh with Crystal, to refresh your memory. The posted pic is Hugh with the new 2012 Playmate of the Year.
