Apparently, Mariah Carey [1] took it upon herself to spruce up my Instagram feed. Over the weekend, the 48-year-old songstress posted a few pictures of her looking incredible in a pink bikini [2] while vacationing in St. Barts with her boyfriend, Bryan Tanaka, and 7-year-old twins Moroccan and Monroe. She poses both in and out of a pool in the snapshots and simply captioned one of them "Happy," followed by a smiley face and red heart emoji. In all of the photos, Mariah flashes a big grin while looking as free as can be in the two-piece.

She certainly has a lot to smile about, considering the past couple of months that she's had. In November, her 15th studio album, Caution, hit No. 1 on Billboard's top R&B/Hip-Hop albums chart [3]. Then, at the very beginning of the new year, her classic Christmas tune "All I Want For Christmas Is You" reached No. 1 on Australia's singles chart [4].

So maybe she's all smiles because she's continued to be a musical maestro for nearly three decades. Or maybe she's just enjoying life. Either way, she looks stellar in the bikini pictures, and we all need to admire them.
