Will Peltz, the son of billionaire investor and food company mogul Nelson Peltz, first started dating Kenya Kinski-Jones—the youngest child of legendary musician Quincy Jones—in late 2011. On Tuesday, Kinski-Jones posted a photo on Instagram of the couple embracing, captioned “JUST ENGAGED. My whole heart for my whole life.”

The couple revealed their engagement in a sweet post on social media that featured Kenya’s diamond sparkler as she planted a sweet kiss on Will, 39.

Kenya is the youngest child of Quincy. Her mother is the German actress and model Nastassja Kinski, who won a Golden Globe in 1979 for her title role in the film, Tess. She is a model who has appeared in runway shows for Chanel and has also been featured in editorial spreads for magazines such as Vogue, Harper's Bazaar, and Nylon.
