The 'Keeping Up With The Kardashians' star is set to wed girlfriend of three months Blac Chyna and pulled out all the stops when he popped the question to make things as romantic as possible.

According to TMZ, Rob covered a room in his girlfriend's house with rose petals and candles, and he got down on one knee and asked her to be his wife when they walked into the room with Blac's mother.

The make-up artist replied "Of course, baby! You know I love you!"

Meanwhile, Rob's family are said to be unconvinced the engagement will last as he has previously professed his undying love for former girlfriends Rita Ora and Adrienne Bailon, and even told his relatives he had proposed to them, though no engagement announcements were ever made.

The 28-year-old star is said to have deliberately kept his family - who flew to Vail on a ski trip hours before he proposed to Blac - in the dark about his engagement plans.

A source described the proposal as "aggressively on the QT."

While the reclusive sock designer's mother Kris Jenner and famous siblings haven't yet spoken about his happy news, Blac's former boyfriend Tyga - who is dating Kylie Jenner - insists he is happy for the couple.

The 'Rack City' hitmaker - who has three-year-old son King Cairo with Blac - tweeted: "Everybody deserves 2 be happy. What some1 does for their happiness is not my concern, as long as it's not interfering wit my happiness.

"It makes me happy to see the mother of my son happy.My only concern in this situation is my son. I want him in happy environments (sic)."
