Selena Gomez  has shared a string of photos from her friend’s pre-wedding beach party.

The singer can be seen frolicking on the beach in a white bikini and embracing her pals.

She captioned the pictures: “My best friend is getting married, so we celebrated her! Future Mrs. Lopez.”

Gomez recently returned with new music for the first time in several months with a song called Anxiety.

She lent her vocals to the track by Grammy Award-nominated singer-songwriter Julia Michaels.

It marks the first music from the US pop star and actress, 26, since she featured on French record producer DJ Snake’s song Taki Taki back in September.

Gomez has previously talked about her battle with mental health issues, and has stepped back from the spotlight on a number of occasions.

The song is featured on Gomez’s frequent collaborator Michaels’ new EP, Inner Monologue Part 1.

Lyrics include: “Feel like Ι’m always apologising fοr feeling / Like Ι’m οut of my mind / When Ι’m doing just fine / And my exes all say that Ι’m hard tο deal with / Αnd I admit it, it’s true.”

In 2016, the Come And Get It and Fetish singer cancelled a number of tour dates and took time away from work due to battling anxiety, panic attacks and depression.
