The long-time friends took part in some hilarious drinking games and also hit the dance floor.
One video shows Adele losing a drinking game and Jen jumping on the singer, while shouting, "how could you lose?" and the host yelled out, "Jennifer, this isn't the Hunger Games."
The Hello singer also revealed what she's been up to recently: "I'm actually at the moment a stay-at-home mum," she told the crowd.
Adele also told the crowd Lawrence is headed down the aisle, "She's f*cking engaged!" over the microphone, in reference to Lawrence's recent engagement to Cooke Maroney.
