With the wedding
set for Saturday, everything's ready for Kendra Wilkinson
to marry her NFL player beau Hank Baskett. But how about the bride? She's likely a little uneasy right now, admits her close friend.
"I think she's probably nervous," bridesmaid Holly Madison said Friday night at Prive Las Vegas while celebrating her Sin City revue PEEPSHOW
But her former Girls Next Door
costar is ready to take the plunge, Madison insists.
The ceremony is "going to be in the evening, and I think it's going to be really beautiful and touching," Madison said a few hours before boarding a flight to attend the event, to be held at her and Wilkinson's former home, the Playboy Mansion. "I'll probably cry."
Even though she is a bridesmaid, Madison
has yet to see the dress she will wear for the ceremony – she's only seen a mockup version
. Not that she's worried.
"I think it will be very pretty," she says.
