Kelly Kay, the model girlfriend of the late Oregon Ducks football star Spencer Webb, just announced she's pregnant … one month after the 22-year-old tragically died.

"We created an angel before heaven gained one ??," Kay said in an emotional post on Instagram. "all you ever wanted was to be a father … I know you'll be the best one from up above."

"Can't believe I have to do it without you but knowing I'll have a piece of you keeps me going," she added. "I can't wait to meet the person that's half you, half me. I love you forever, both of you," she continued.

As we previously reported, Webb — a tight end with the Ducks — died after he fell and hit his head during an accident at Triangle Lake in Oregon.
