On Tuesday, the 25-year-old pop star posted a carousel of photos that marked her return to Instagram.
In one of the slides, the "Havana" chart topper rocked a tiny blue string bikini while visiting a beach in Miami with her besties. She accessorized with a beaded necklace and gold hoop earrings, while her raven-coloured locks tumbled in loose waves across her shoulders.
Cabello also posted snaps of her pup, Tarzan — whom she shares with ex-boyfriend Shawn Mendes — and a video of her and her friends enjoying a late-night meal with music in the background.
"305 till I die," she captioned the post, which refers to Miami's area code.
Fans were thrilled with Cabello's return to social media and loved to see the star having fun with her friends.
"You look absolutely stunning and gorgeous. The queen of the beach!" wrote a fan.
"Yes! Welcome back to Instagram!" commented another follower. "So good to see you having fun and living life!"
"Thank gosh my queen is back! And looking as stunning as ever!" said another.
"Looking fire!" wrote another fan. "Have a blast!"
"Can I join you on the beach?" said someone else. "I'm also loving that blue suit on you!"
Earlier in the day, Cabello posted a video of herself to her Instagram story wearing a skin-tight black mini dress with a halter neckline. The songstress added a matching long-sleeve bolero and styled her hair in a top knot. To accessorize, she rocked the same beaded necklace but swapped out her chunky gold hoops for thin silver ones.
"I'm back from my social media detox," she captioned the clip, which saw the star use a playful filter that gave her horns on the top of her head.
