The couple even got tattoos of each other’s names while they were dating. Bailon got her tattoo of Rob’s named finally removed in 2014.
That same year, Bailon stirred up some controversy with the Kardashian sisters when she opened up about her previous relationship with Rob to Latina magazine. The host, actress and singer said getting “stuck with that Kardashian label” was “so hurtful to me and my career.”
Bailon later told E! News, “I never meant any harm with anything I said,” adding, “I think they’re amazing people.”
It was revealed in January that Rob is currently dating Blac Chyna. Chyna shares a 3-year-old son with Jenner’s boyfriend, Tyga.
Things appear to be getting serious between Rob and Chyna. Rob gifted Chyna with lavish presents earlier this month on Valentine’s Day and the pair has appeared in public together often in recent weeks.
