I just posted my 88th "Making Babies" entry recently, and Cartman brought up about #100 fast approaching. Then he asked me today who it's going to be. Sadly, it won't be his favorite, Hayden Panettiere, since I already did her.
I haven't even decided who will be featured in "Making Babies 100" myself yet. It won't even be out until my September cycle.
But feel free to help me out. Check under Consensual & Sensual and see who the first 88 celebrities were [the very first story was Britney Spears], and PM me a female celebrity or celebrities that hasn't been featured yet, past or present. I'd say the cutoffs for request should be August 15th, more than enough time for you to get your request in, and thanks!
