According to an E! insider, the group were said to be making the most of their time together whilst in Cabo.

By night the group watched a private fireworks show as they dined on the beach together.

The powerful duo joined forces for the song Anxiety on Julia’s latest album Monologue Part I, with Selena singing the lyrics, ‘But all my friends, they don’t know what it’s like, what it’s like. They don’t understand why I can’t sleep through the night.’

The new sounds marks the first time Gomez has released music since she sought mental health treatment late last year.

Julia’s new album Inner Monologue Part 1 was released on January 25 and also includes the song What A Time featuring Niall Horan.

While Selena is in good spirits, her ex Justin Bieber is currently struggling with a bout of depression.

Her former boyfriend, who recently married Hailey Baldwin, is undergoing counselling to help him ‘figure out his next chapter’.

The As Long As You Love Me hitmaker has been feeling down and tired as of late and is reportedly seeking some help to discover the ‘root issues’ that have been affecting him.

Justin had previously opened up about how becoming so famous at such a young age had a negative effect on his mental health.

He shared: ‘I started really feeling myself too much. ‘People love me, I’m the s**t,’ that’s honestly what I thought. I got very arrogant and cocky. I was wearing sunglasses inside … I found myself doing things that I was so ashamed of, being super-promiscuous and stuff, and I think I used Xanax because I was so ashamed.’

Selena and Justin dated on and off for years and last spent time together in March last year. Three months later he was hanging out with his OTHER on-off companion Hailey Baldwin, and they got engaged in June. They married in a court house ceremony in November.
