The "Good For You" singer doesn't seem bothered by her ex's new relationship.
While Justin Bieber was vacationing with his new girlfriend, Hailey Baldwin, his ex Selena Gomez had a getaway of her own.
On the same day that the "Sorry" singer posted a pic of him kissing Stephen Baldwin's daughter, Gomez shared a sexy bikini pic of herself posed with a few of her gal pals.

"Left my phone behind to be present! I am so grateful for the people I've met this year but more importantly for the people who have been consistent and by my side through thick and thin," the "Good For You" singer Instagrammed to her 59.1 million followers. "That'd be YOU. Thank you for another year! Love you guys!"
Baldwin and Bieber posted a slew of PDA pics over the holiday season, but the 21-year-old pop star made it official when he shared an image of him locking lips with the 19-year-old model.
Gigi Hadid -- who is dating former One Direction member Zayn Malik -- excitedly reacted to the Instagram pic, writing: "Okay, I'm SO down for this. Been with Z today, f**k it up Hails! Double date is definitely happening!"
While Bieber is fueling the romance rumors, Gomez has been shooting them down. When the "Hands to Myself" singer spoke with ET in December, she denied reports that she was dating One Direction member Niall Horan. "Oh my god! No," the 23-year-old clarified. "I love him, I always have. He's amazing."
