The families of Jojo Fletcher and Jordan Rodgers celebrated their engagement together over the weekend in a surprise party. Jordan’s estranged brother did not attend. JoJo wrote on Instagram:

"My heart is so full! Jordan and I were going out to what we thought was just a little dinner with friends but instead walked into a room full of both our friends and family to celebrate in our engagement. We are so incredibly blessed. #fletchersmeettherodgers."

The best thing to hold onto in life is each other.... & tacos. ❤️👫🌮   A photo posted by JoJo Fletcher (@joelle_fletcher) on

Entertainment Tonight claims Jordan Rodgers' ex-girlfriend, Brittany Farrar, is attempting to prove he cheated by posting actual receipts online.  The picture shows a receipt for flowers that reads: "Happy Birthday to my Favorite Bella. Miss you. Can't Wait to To See That Beautiful Smile Again. From, Your Favorite Football Player Wanna Be Actor." Brittany Tweeted:

"With the power of a press tour, his lies reached our hometown. His choice has become other people's consequences. So if I don't have a choice in whether people back home are talking about me, then I might as well have my voice in this. Unlike Jordan, I'm not going to sell stories to magazines. Instead, I'm posting right here. Because to me truth is not about fame."
