Nicki Minaj is feeling cheeky! To celebrate Valentine's Day, the hip-hop superstar shared three racy pictures of herself wearing a neon thong bikini via her official Twitter account on Thursday, Feb. 14.

"Happy Vag Day boys," Minaj wrote in the caption, who cautioned her male fans to "jerk responsibly." In one image, the "Starships" rapper squatted near the edge of a pool while surveying her tropical surroundings.

Though the 30-year-old American Idol judge has never been shy about showing off her juicy booty, staying in shape has been a challenge for the New York native.

"I'm naturally petite, but I definitely struggle with keeping those extra pounds off," the 5-foot-2 star told Allure in April 2012. "And I hate working out. I can't stand being on a treadmill. That mentally irks me. When I need to lose a few, I just cut out sugar and starch."

When she's not making headlines for her over-the-top appearance, Minaj is earning raves for her insights on American Idol. On Thursday, Feb. 14 -- the same day she shared the risque pictures with her Twitter followers -- Rolling Stone's Rob Sheffield called Minaj "the best judge" the Fox talent competition has ever seen.

"Minaj comes off as sincere and devoid of bullsh-t, zeroing in on the right contestants. She seems like the smartest person in the room, even though she's a nonstop cartoon montage of candy-colored wigs, space-hooker costumes and ridiculous accents," Sheffield wrote. "Mariah Carey looks like a stiff sitting near Minaj . . . It's Minaj who deserves all the credit for firing up the singers and revitalizing the format."
