Cardi B launches hair line as split rumours with Stefon Diggs swirl

Amid swirling rumours about her relationship with NFL star Stefon Diggs, Cardi B announced a milestone of her own: the launch of a haircare brand called Grow-Good Beauty, a project she says she’s been quietly developing for years. The 33-year-old rapper shared a teaser on social media teasing products inspired by her own hair journey and the DIY remedies she’s long talked about.

Cardi’s announcement leaned into the personal: she told fans that, as a youngster, she struggled with her hair and that Grow-Good Beauty is born out of that history and years of experimenting. She added that she’s worked on the line for around three years and even teamed up with scientists to turn kitchen tips into formulas she hopes will actually deliver results. The tease and the promise of practical, growth-focused products, quickly lit up her timelines.

The timing of the reveal has drawn attention because it came just after fans noticed Cardi and Diggs had unfollowed each other on Instagram, which fuelled split speculation. Entertainment outlets and insiders told reporters the couple’s social-media move, plus Cardi’s cool response to questions during Super Bowl weekend, stoked talk that they’d recently separated — though some sources suggested the split might be temporary and that reconciliation remains possible.

Cardi and Stefon first made their romance public in mid-2025 with a high-profile courtside appearance, and they welcomed a baby boy together in November 2025, details that made their relationship one of the more talked-about celebrity pairings of the year. Even so, high-profile relationships can move quickly between public moments and private recalibration, and fans have been watching closely for signals from both stars.

For now, Cardi appears to be leaning into work and celebration. The Grow-Good Beauty announcement arrives as she prepares for a new leg of her public life, including tour dates and high-visibility appearances, and the product news offers fans something positive to rally around while rumours about her personal life continue to circulate. Whether the couple will sort things out privately or make a public statement remains to be seen; until then, Cardi’s new venture and the heartfelt, often messy realities of celebrity relationships are sharing the spotlight.

What to watch next: official launch details for Grow-Good Beauty (products, pricing and where to buy) and any comment from representatives for either Cardi B or Stefon Diggs, both of which will likely settle some of the current speculation.
