Cruz Beckham's girlfriend Jackie Apostel celebrates singer's new milestone

Cruz Beckham has been working on his album for a while and has finally released the first single, along with a music video, and his girlfriend, Jackie Apostel, is the most excited.

The 20-year-old musician, who followed in his mom Victoria Beckham’s footsteps to choose his career, met Jackie because of his passion for music too.

The German-Brazilian singer and model, 29, took to Instagram to write a heartwarming tribute to Cruz and their relationship.

"We first met when we were put into a studio by our managers to write some songs together. I was told you had been working on your own project for ages and shifting sounds a bit, finding yourself,” she wrote, sharing his post announcing the song, Optics, which was just released along with Lick The Toad.

Jackie went on to share how their creative collaboration “became friendship and friendship became us.”

Hinting at the next few tracks, she teased that these songs “are just a fun little warm-up.”

She concluded, “I am so proud of you. I love seeing you do everything you said you would. I am your biggest fan forever. I love you.”

The songstress also shared the behind-the-scenes shots from the music video she is credited as a brand strategist on, and wrote, "A day in the country, a craigslist couch and a couple friends.”
