Model Hailey Baldwin and her ex-boyfriend Justin Bieber are engaged.

However, Selena Gomez posted a number of bikini photos on her Instagram account on Wednesday and didn’t appear in the slightest bit phased.

On a boat with friends, the stunning 26-year-old singer and actress showed off her cleavage and flat tummy in a vibrant string bikini. 

The Monte Carlo actress flaunted her chest in a low-cut bikini top with a bow design in the centre. The number had a green and blue pattern.

In one photo, Selena held fast to the string on her bikini panties as she posed.

With her brown strands falling loose around her, the beauty wore gold hoops earrings.

Selena wore minimal makeup, only a hint of mascara and a pink lip colour.

Selena was sitting close to the back of the boat, leaning on a friend, and she couldn’t help but smile. 

Selena was seen in another picture from her slideshow wearing dungarees over her bikini and her hair pulled back.

In a different photo, the Back To You singer grinned while posing in the car with friends.

She looked cute in the picture, sporting a graphic T-shirt.
