Selena Gomez shelled out $30,000 on a birthday party for her boyfriend The Weeknd

The surprise party - which was held at Dave & Buster's in Hollywood - was attended by the singer's pals including French Montana, Big Sean and 2 Chainz.

The group had exclusive access to the venue from 11pm until the early hours of the morning but Selena was unable to make the event as she was in NY for New York Fashion Week, TMZ reports.

Whilst the 24-year-old singer was unable to attend the party, Selena and The Weeknd - real name Abel Tesfaye - spent some time together on a romantic yacht trip over the weekend.

A source said: "Selena looked happy and in a romantic mood. The Weeknd looked happy and very amorous. They were very intimate and looked very much in love."

Whilst another insider added: "They are falling for each other. He has told [Selena] how much he cares for her.

"[They have a] crazy connection. Selena feel really confident. Abel is proud to have Selena by his side ...

"He really likes her. They text every day. They have a really sexy and flirty relationship. They laugh and like each others personalities. As of now, they are just having fun and enjoying each other.

"She is happy and doesn't mind sharing that with the world. Abel makes her feel secure and Selena has nothing to hide. Selena gets passionate about things real fast and that is exactly what she is doing with The Weeknd."

The pair first fuelled speculation they were dating after they were seen kissing outside Giorgio Baldi restaurant in Santa Monica last month.
