Are Holly Madison & Criss Angel Hunting for an Engagement Ring?

Will there be a double wedding at the Playboy Mansion this summer?

Just three days after "Girls Next Door" star Kendra Wilkinson announced that she and Hank Baskett will get hitched at Hugh Hefner's famed estate on June 27, fellow costar Holly Madison was spotted looking at rings in Las Vegas with her "Mindfreak" boyfriend, Criss Angel.

An eyewitness tells me Madison and Angel hit Berger & Son Fine Jewelers in the Fashion Show mall at about 5pm on Christmas Eve.

"They were looking at one ring and Criss said, 'Would you marry me?' " our spy reports. "Holly didn't say anything. She just looked at him."

But then the couple saw that a crowd was beginning to form in front of the store, so they quickly took off.

"Criss handed the ring back to the sales guy and said, 'Thanks,' " the spy said.

Reps for Madison and Angel say we shouldn't go looking for their wedding registry just yet. "Criss bought Holly a ring for her birthday," Madison's rep said. "It's a flower ring."

Darn it! We were hoping to see Hef walking both Wilkinson and Madison down the aisle at the same time.


Meanwhile, I'm told Madison and Angel's families met for the first time last week when they celebrated Christmas together in Vegas.
