In the clip, Chyna is seen cruising while wearing a camouflage T-shirt and rocking perfectly-curled hair. The 28-year-old model mouths along to the song on her radio, before blowing a kiss to the camera.

Earlier in the day, Rob spent time with one of his other favorite ladies -- sister Khloe Kardashian. While it definitely got a bit rocky between the two after Rob proposed to Chyna in April and failed to tell his family, Rob and Khloe have clearly patched things up. Rob and Chyna attended Khloe’s 32nd birthday bash at Dave & Buster's in June and everything seemed to go well , with the three even posing for a picture together in a photo booth.

This week, the siblings also spent some quality time together and hugged it out, as seen in a picture on sister Kim Kardashian's Snapchat.

Khloe also posted a video of her and Kim goofing off with Rob in between them.

Of coarse, when Rob isn’t with one of his five sisters, he is showering Chyna with love. In May, the sock designer showed his future wife how much he cared for her on her birthday by sending her 28 roses for the 28 years she’s been alive.

"28 bouquets of flowers with 28 reasons why I Love Her for her 28th Bday‼" Rob captioned the cute video revealing Chyna's reaction to his gift. "HAPPY BIRTHDAY ANGELA!! Awwwww I'm the best ‼️????? I LOVE YOU !!"

Chyna is definitely one lucky lady when it comes to being pampered by her man. ET recently caught up with Chyna and she revealed that she thinks Rob will be an "overprotective" dad.
