While Shantel Jackson had a long past with Floyd Mayweather, the demise of their relationship played out for all to see on Instagram, as Mayweather blasted Miss Jackson for terminating a pregnancy around the same time she moved on to rapper Nelly. Mayweather has since moved on as well, but this weekend was all about Miss Jackson, who took to IG to thank her STL boo for making her birthday weekend "Incredible."

Shantel took plenty of pics of her birthday activities in The Hamptons, and wrote this heartfelt message to Nelly as the caption to one of the couple's romantic flicks:

"I have had more fun this weekend than I have in years. I am so grateful that I got to spend my birthday with my family and friends, all thanks to this amazing man @derrtymo Thank you so much for making my weekend incredible. Nothing is more important than having real people in your life and no amount of money can buy real happiness. My weekend was priceless and filled with great moments and memories. #missjackson #leo #birthdayweekend #family#friends #hamptons #nyc #1oaksouthhamptons"
