Shortly after receiving the historic news, Sam smashed cake in Cammisano's face and kissed him.
Cammisano also tweeted this photo of the two of them:
Here's another post by Cammisano celebrating Sam:
Both Sam and Cammisano graduated from Mizzou. Cammisano, too, was an out gay athlete there, competing on the school's swim team. Here they are at a Mizzou basketball game where Sam received a standing ovation in February.
And here they are in a Feb. 10 post — the day after Sam publicly came out as gay.
On Easter, the couple sipped mimosas at brunch.
And here they are looking spiffy at a beach in Santa Barbara.
Oh, and here they are after running 6 miles last week.
And just last Thursday, the first day of the NFL draft, the two woke up in San Diego and took a snuggling selfie.
Watch the couple kiss and embrace when Sam gets the news:
