The Black and Yellow hitmaker broke the happy news to fans via Twitter.com on Monday afternoon (08Jul13), six days after obtaining a marriage licence in Los Angeles.
He tweets, "Me and Amber got married today. Weddings this fall. Thought I'd let yall know (sic)".
His new wife followed up the announcement by sharing her own message with fans online, writing, "Yay me & my Baby are officially married!!!"
Khalifa recently revealed the couple is planning to celebrate its love with a big wedding this autumn (13), once Rose regains her pre-pregnancy figure following the birth of their first child, son Sebastian, in February (13).
He told America's Sister 2 Sister magazine, "She wants to look perfect in her dress. She doesn't want her dress to fit her 'after baby' body. She wants it to fit her regular body."
The pair began dating in 2010, following Rose's split from Kanye West, who also became a new parent when his girlfriend Kim Kardashian gave birth to their first child last month (Jun13).
