"Me and Amber got married today," he wrote. Khalifa added that they plan to throw a bigger celebration later this year. "Wedding's this fall," he said. "Thought I'd let y'all know."
Rose, 29, also tweeted about their union, writing, "Yay me & my Baby are officially married!!!"
Khalifa and the model have been together since early 2011 and became engaged in March 2012. They welcomed their first child in February 2013.
The "Black and Yellow" rapper had first shared his plans to quietly tie the knot with Rose during an interview with NYC radio station Hot 97 in November 2012. "We're gonna get, like, licensed marriage, in a couple weeks we'll have that done," he said, explaining that they would have a big celebration after Rose gave birth. "When you have the ceremony, that's when you can invite the family. She can fit into a dress . . . If we have a daughter one day, she might wanna give the dress to our daughter, but if she's pregnant then she can't do that."
Khalifa also joked that they were going to postpone the wedding so Rose could properly toast her big day. "She wants to get drunk," he joked.
