This new bombshell is bringing the shade!

During Ariana Madix’s “Love Island USA” debut Tuesday, the “Vanderpump Rules” star dissed her ex-boyfriend Tom Sandoval.

“I can’t wait to see who’s actually been taking the time to get to know one another,” the reality star, 38, told the competitors while hosting the “Mr. and Mrs.” game.

“Take it from me, it’s important to know who you’re dating or sharing a bed with,” she continued. “And if they’re not the one for you, trust me, it’s better to find out sooner rather than later.”

Not only was Madix referencing Sandoval’s months-long affair with her friend Raquel Leviss, but she appeared to have a specific conversation in mind from before their breakup.

In a May episode of the Bravo show, the actress spoke to the 41-year-old cover band frontman about her desire to spend quality time together.

“I don’t have time to watch 50 goddamn episodes of ‘Love Island,'” Sandoval replied. “That is your definition of quality time, not the definition of quality time.”

As for his definition, the Schwartz & Sandy’s co-creator wanted to skinny-dip, “take some mushrooms together and watch the sun rise.”

Since the duo broke up in March, Madix has dragged her ex in multiple ads, from promoting GLAD trash bags to selling T-Mobile upgrades.

News broke earlier this month that she would make an appearance on Season 5 of “Love Island USA,” which is hosted by “Modern Family” alum Sarah Hyland.

Madix gave a glimpse of her cameo on Monday with Instagram photos of herself sitting by the show’s iconic fire pit in a body-baring white dress and matching sandals.

“I can’t believe i’m popping in the @loveislandUSA villa this week!” she gushed. “like.. i am GATHERED around the fire pit! you can watch the fun on @peacock.”

During Tuesday’s episode, Madix rocked another revenge dress, pairing a shiny blue number with gold heels.
