Part of the family! Kourtney Kardashian is still extremely close to Adrienne Bailon, despite her relationship with Rob Kardashian fizzling out back in 2009. The Real host attended a lavish poolside party for Poosh, where attendees got to relax with massages, lounge in hammocks and try all of Kourt’s favorite products. After a fan insulted Adrienne in the comments, the Keeping Up With the Kardashians star jumped in to defend her pal.

“Never forget Adrienne dips tuna sandwiches in Hawaiian Punch,” a follower wrote on a photo of the ladies wearing matching Onia swimsuits while splashing in the pool alongside Yris Palmer, fitness trainer Amanda Lee and model Nicole Williams. The comment is in reference to a recipe video the former Cheetah Girls star made of her favorite “weird food” combinations — one of which included adding a splash of the fruity red beverage to her tuna salad.

“If [Adrienne Bailon] does it, I’m doing it. Still sis for life,” Kourtney, 40, clapped back. That’s what friends are for, right?

Adrienne, 35, frequently shows the Kardashian sisters a lot of love on social media and she raved about Kourtney’s stylish party in the comments. Spoiler: She was unbothered by the fruit punch flavored tuna comment. “The best time! [Poosh]! The most stunning [and] chic Saturday … EVER! Ha. So YOU! Love you, hermana,” the former 3LW songstress sweetly wrote.

After a fan mentioned that Kourtney should be a guest on The Real, the reality starlet responded with a pair of eyes emoji, so we’ll take that as a definite maybe.

Rob and Adrienne dated for two years and split after he cheated on her — an incident he later confirmed on KUWTK. The King Arthur founder then pointed the finger back at his ex and said she “was cheating and having sex with so many different people” while they were dating.

“I absolutely never cheated on Rob. And I just want to clarify that,” the singer said on her talk show after the accusations. “And the way it’s said — it’s like, ‘She slept with many people.’ I’m like, ‘Uh, I can’t speak for anybody else, but I can assure [you] that was not me.'” Adrienne married musician Israel Houghton in 2016.

Although things didn’t work out with Rob, it looks like Adrienne is still tight as ever with the Kardashian fam!
