Holly Madison and Kendra Wilkinson are much more than two-thirds of the occasional threesome.
These two Playboy models are true friends, as Kendra has asked Holly to serve as a bridesmaid in her wedding to Hank Baskett.
"I'm really excited about it," Madison said. "If she needs any help planning, I'll pitch in. It's going to be a really great event – it's going to be amazing."
Holly added that she can see a difference in her often-naked pal since she started dating the Eagles wide receiver.
"Ever since they met, I've just seen a difference in Kendra: she's matured, she's a more compassionate, considerate person," said Madison. "She's just grown up so much and just to see what he brings out in her is just amazing."
Holly herself, meanwhile, has found a new man: creepy-looking magician Criss Angel.
"I'm really, really happy," Madison said about the rumored ex-lover of Britney Spears, Lindsay Lohan and others. "He's really, really fun, really sweet – he's so amazing to be around."
