Tina Lawson is a prime example of a 'proud mom.' Her Instagram is filled with endless posts of Beyonce and Solange's successes and even close family friends who have grown to become her soul children like Kelly Rowland and Michelle Williams. "Could anyone be more gorgeous than this angel!! Beautiful black Barbie Doll," Tina captioned a photo to her feed of Kelly. 

Tina's latest Instagram shout-out is for her lovely son-in-law, Jay Z, in light of his 49th birthday that was yesterday. The loving mom shared a photo of Jay from The Global Citizen Festival this past weekend with a caption that detailed just how close the Carter's and Lawson's have clearly gotten over the years, despite some expected ups and downs. 

"A very Happy Birthday to my amazingly talented, super smart, gracious, classy, filled with swag son in law. I have witnessed your loyalty to all of your friends, some from childhood if only we all could be so supportive of our friends and share a mutual love and respect for each other like you and your amazing friends," she wrote. "You have done so much for our Culture, Thank you for that! I could not be more happy to have you in my family and could not be more happy to be in yours. (Gloria and Grandma Hattie you did great). I have watched you grow personally in leaps and bounds and you are an incredible husband and the best Father! I love you."
