Has anyone heard of celebrities getting Thermage?

I have been reading lately, that celebrities who don't want to go under the
knife have tried more noninvasive procedures like Thermage. Has anyone
tried this and does it work. I went www.Thermage.com and it was
informative, but it doesn't claim to have been used on celebs. Not that I
would do it only cause celebs have it done. I just am curious which ones
have had it done to compare. BET
