Porsha, 37, who is expecting her first child with Dennis McKinley, took to social media to post a lengthy birthday tribute to her younger sister, Lauren, 31.
At the end of the loving letter, the mama-to-be told her followers not to "judge" her grammar because she was writing while lying down in the back of an Uber!
"Don’t judge my grammar I'm in the back of an Uber, laying out on my way to work because PJ won’t let me sit up and drive lol," she wrote.
Before her confession, the Real Housewife gushed all about her little sister!
"Happy 31st Birthday to one of the most beautiful humans @lodwill! Yes we joke about me being obsessed with my mini me but honestly I’m so proud of my little big sister! My lil sis is an amazing mommy, a loyal, loving sister and a devoted daughter," Porsha said.
"Lauren is someone I think each person around her looks up to for one reason or another," the star said. "Sometimes she can be silly and crazy that’s 'Lo' and other times it’s like she’s been here before and is the wisest confidant you can have. I thank God making me a built in bestie and business partner! Love you long time!"
