Following the ceremony, Love shared a photo of the two in a convertible. "Just married!" she exclaimed.
Brandy, who was one of Love's bridesmaids, took to Instagram on Friday to individually gush over her brother and new sister-in-law.
"@PrincessLove you are very loved and you have been a butterfly your entire life even when you didn't know it... It's your time to fly, you have wings," she captioned one of the pics, using the hashtag, "#IseeYou."
Brandy called her brother a "#Champion" for beating "concrete" and defying "all odds."
Snoop Dogg also congratulated the newlyweds, writing, "Congrats to my cousin @rayj and princess."
The R&B singer proposed last December to Princess Love on the tarmac of an airport in front of a small, private plane. The two had been dating for about a year.
"It was all a surprise — she had no idea," Ray J told OK! Magazine after the proposal. "We were going to Arizona; I got the private jet and called her best friends and parents to come out the day after Christmas, and they hid on the plane...I pulled out the ring, and I started crying."
"She knows where my heart is and the connection we have. She's a true ride-or-die woman for me," he added.
And they've been documenting their love ever since.
Ray J is not the only famous star to have recently tied the knot. Tatyana Ali, best known for portraying Ashley Banks on The Fresh Prince of Bel-Air, married her boyfriend, Dr. Vaughn Rasberry, in July.
The 37-year-old actress, who is pregnant with the couple's first child, celebrated her big day at the Four Seasons in Beverly Hills, California.
