Kate Gosselin won't admit to dating millionaire Jeff Prescott let along being engaged to him.

Gosselin's jewelry choice had everyone talking over the weekend when she sported a diamond ring on that special finger at the TLC Summer Block Party in Philadelphia.

The 40-year-old reality star quickly shot down speculation that Prescott (or anyone else for that matter) had popped the question in a tweet on Monday.

The mother of eight also denied having any current romantic relationship even though she and Prescott have been spotted out together multiple times since January. Her rumored boyfriend is the COO and co-founder of Dreamstine, a microstock photography agency.

Gosselin divorced Jon Gosselin, the father of her children, in 2009. She's previously been linked to her bodyguard, Steve Neild.
