The 'Keeping Up With The Kardashians' star was joined by his family at a private screening of the Disney live-action movie - which stars Emma Watson and Dan Stevens in the titular roles - on Friday (17.03.17) to celebrate the big day.

Kris Jenner hosted the event, hiring out a movie theatre in Westlake Village, California whilst Rob's sisters Kourtney and Khloe Kardashian also attended.

Rob's on/off fiancé Blac Chyna was also in attendance, bringing their four-month-old daughter Dream along, but she reportedly left soon after with a nanny. Chyna was seen carrying two huge gold and black balloons in the shape of the numbers '3' and '0' as well as a small birthday cake and a series of presents wrapped in gold paper.

Meanwhile, Kourtney brought her brother a basket full of gifts and a card addressed to 'Bobby'.

Because Rob's birthday fell on St. Patrick's Day, guests were given a series of shamrock-related costumes for people to dress up in.

During the movie, the group dined on popcorn and other movie-related snacks, Us Weekly reports.

It comes after Chyna insisted she is "in it for the long haul" with her on/off fiancé Rob.

She said: "I feel like every person who's in a long-term relationship, or who is committed to their person, goes through ups and downs. Everything isn't always going to be peaches and cream. If it is, then it's fake. I'm in it for the long haul, so I feel like my advice [for anyone in a similar situation] is therapy, know each other's family, calling each other's moms.

"I feel like everything isn't going to be perfect, but I know we love each other and we're fighting for each other, and the people we surround ourselves with are rooting for us. It makes everything much easier."
