Kris Jenner Shares Sweet Message For Son Rob Kardashian's Birthday

Happy birthday, Rob Kardashian!

The Rob & Chyna star turned 30 years old on March 17, 2017. To celebrate, Kardashian's mama, momager Kris Jenner, shared a collage of both old and recent photos on Instagram alongside a sweet message for her only son.

"Happy birthday @robkardashian!!!! I love you more than words can say," Jenner wrote. "You have the sweetest soul and the kindest heart, and I am blessed beyond measure to call you my son. I am so proud of the man you have become and it brings me so much joy to watch you grow as a brother, son and father."

"There are so many blessings in this life," Jenner continued, "but being your mom is one of the greatest. I love you!! #HappybirthdayRob."

While there have been no posts on Kardashian's account to indicate what he's up to on his milestone birthday, he did share a glimpse into his life on March 16, 2017 with a photo of the inside of a gym. He captioned the image "There's No Place I'd Rather Be," a phrase emblazoned on the gym wall.

Kardashian has been keeping busy lately. The Arthur George founder has reportedly been exercising with celebrity trainer Gunnar Peterson in an effort to get healthy while he prepares for a custody battle with ex Blac Chyna over their daughter, Dream. He's also been seen hunting for a new home in Encino, Calif.
