Selena Gomez is "very grateful" after hitting 110 million Instagram followers

Captioning a photograph of herself standing on stage in front of thousands of fans, she wrote: "Thank you fam for 110. I promise I will continue to cherish my platform and speaking truth but more importantly, each and every one of you have changed my life. I'm very grateful."

And Selena has another reason to celebrate as her romance with The Weeknd is going from strength to strength.

The 24-year-old singer recently shelled out a hefty $30,000 on a birthday party for the 'Can't Feel My Face' singer. The party was held at Dave & Buster's in Hollywood, which was attended by the singer's friends including French Montana, Big Sean and 2 Chainz.

Whilst Selena wasn't able to make it to the party, she was seen with him on a romantic yacht trip.

A source said of the couple's romance: "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 an 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."
