Amy Schumer seemed like she had a blast hosting Saturday Night Live this weekend, but the after-party was where the real fun went down!

The Trainwreck star was joined by her famous BFFs Jennifer Lawrence and Aziz Ansari at The Wayfarer in the heart of New York City, where they partied until the wee hours of Sunday morning. J.Law gave Aziz piggyback ride at least a portion of the way there, but as one onlooker told E! News, it was Amy who "was having the best time."

The Inside Amy Schumer star, 34, "spent most of the party sitting at a table in the back with [SNL creator] Lorne Michaels," said an insider. Jen, 25 was "hanging out" with Aziz, 32, and a group of pals until around 3 a.m., when she made her way over to Amy and Lorne's table and chatted with them for about 15 minutes. According to an eyewitness, the Oscar winner "left earlier than everyone," which was still not until around 3 a.m.

"Amy was one of the last to leave," added the insider. "She stayed until 4:30 a.m. and even said she was headed to the after-after party," which reportedly tok place at Cabin.

SNL's musical guest The Weeknd was also joined by girlfriend Bella Hadid at the after-party. Although an onlooker noted there were no overt signs of PDA between their pair, it was noted they were definitely together.

All in all, sounds like a fun night!
