"Yay me and my baby are officially married!!!" the 29-year-old Rose tweeted.
Khalifa, 25, kept his announcement even more casual, adding that they would host a wedding party later this year.
"Me and Amber got married today. Weddings this fall. Thought I'd let yall know," he said.
The "Black and Yellow" rapper proposed to Rose in March of last year.
"She Said Yes!!!" he captioned a Instagram photo of his new fiance wearing her engagement ring.
