Probably not much, but...
Both are celebrating their birthdays today! The reality-TV mom turns 37, while the pop superstar is 26.
"My kids often remind me how old I'm getting with comments like, ‘You were born in 1975, Mom?!!'" Gosselin writes in her latest blog post for CouponCabin.com. "'Wow, that was a loooong time ago! It was last century!'"
"Mady has repeatedly announced, 'You're 37 with no wrinkles,' as if reminding me of my new age AND that wrinkles are around the corner is a NICE thing to say!" she continues. "I told her to get her eyes checked because I, in fact, have plenty of wrinkles!"
As for birthday gifts, Gosselin writes, "My kids each hand made me an adorable card and hid them under their beds until they couldn't stand it anymore. They've already presented them to me a bit early and I LOVE each cute little creation!"
"Happy Birthday to me. Now if only this extra year could be traded to someone who is looking for an extra one…I'd give it to you for a really great deal! Any takers?"
Here's to another great year, Kate!
