According to sources, the asking price for the model and former World Wrestling Entertainment personality to attend events has more than doubled, as she's now the A-list star's companion.

Planners are saying that Keibler, who used to ask around 10,000 dollars for personal appearances at events and parties, is no longer going for less than 25,000 dollars.

"Stacy's fee has gone up dramatically," a source told the New York Post.

Another source theorized that her appearance fees "are higher because they [event organizers] hope Clooney might show up."

One insider also revealed that Keibler recently had agreed to a 10,000 dollars hosting fee for an anniversary party - but following repeated appearances with Clooney on the red carpet, she came back to organizers demanding 25,000dollars for the gig, a 150 percent mark-up. (ANI)
