Selena took to Instagram on Friday to hype up the upcoming release of her sixth studio album, Rare, and share some final looks at her Hawaiian New Year vacation.
In the first of her series of two posts, the star shared a photo laying down on a bed.
Gazing at the camera, she kept a straight face.
‘Feels so good to dance again #7DaysToRare’, she wrote in the caption, hinting at her album’s January 10 release.
Selena rang in the New Year with a Hawaiian vacation on a private yacht.
The former Wizards of Waverly Place star posed on the side of the boat as the sun set behind her.
‘Hi New Year. Let’s make this one better than the rest,’ she wrote in the caption.
Selena was previously in a nine-year on-off relationship with Justin Bieber, 25.
The couple split in March 2018 – just three months before Justin began his whirlwind romance with Hailey, 23, who he married in September 2018.
Selena recently encouraged her 164 million Instagram followers to donate to support those affected by the wildfires which continue to rage in Australia.
‘Absolutely devastated by the fires in Australia,’ the pop star wrote.
‘Praying for everyone affected and all of the first responders. I’m making a donation and would love if you would consider doing the same if you can.’
