Cardi B celebrates her birthday in ‘F—k it’ sweatshirt 

Cardi B is 30, flirty and thriving.

The “WAP” rapper marked her birthday on Tuesday with a pantsless Instagram photo of herself wearing a sweatshirt emblazoned with a strong message: “F–k it.”

The $125 DKNY style comes printed with the prompt “Today I Feel,” along with a slew of iron-on stickers featuring adjectives like “iconic,” “strong,” “fearless” and “powerful,” so shoppers can customize their crewnecks.

It seems that Cardi, however, chose to go rogue by scribbling on a message of her own in rainbow colors.

“Some days you gotta just say F*** IT. So many things are out of our control and instead of spending time worrying about how to fix it or make it better, you gotta just throw ya hands up and say F*CK IT,” she began the caption of her post, which was created in partnership with the fashion label.

The famous Libra added that she wanted to “let you guys know that sometimes you gotta just roll with the punches and start over TOMORROW!”

“Cardi can put anything on and it will look good on her,” one fan quipped in the comments.

The “Up” hitmaker’s not the only star to snap a pic in one of the sweatshirts, which are part of a collaboration between DKNY and the National Alliance on Mental Illnesses (NAMI); Tommy Dorfman posed in a version reading, “Today I feel adventurous,” while “The Summer I Turned Pretty” star Gavin Casalegno personalized his to read, “Today I feel loved.”

Despite its bold message, the sweatshirt’s a surprisingly casual (not to mention covered-up) choice for Cardi, who recently bared her butt in a plunging dress and rocked a $3,000 velvet catsuit.

Perhaps the face-tatted fashionista plan to tone down her style as she heads into her 30s. After all, as she’s proven time and time again, she’s not afraid to say, “F—k it.”
