Caitlyn Jenner Keeps up with her grandkids 

Stepdaughter was congratulated by the former Olympic gold medalist Khloe Kardashian after she and ex-boyfriend Tristan Thompson welcomed baby No. 2 via surrogate.

“Congratulations major @khloekardashian,” Caitlyn tweeted Aug. 5 alongside CelebHomes News’ article about the birth of Khloe’s baby boy. I love you so very much. Your strength is amazing. What a remarkable mother!”

Fox News’ contributor shared an additional message on Instagram to Good American CEO: “You are an incredible mother and such an impressive boss woman!” Truly incredible for women everywhere – so blessed to have you in my life!”

Caitlyn’s post comes after Khloe’s rep told CelebHomes News that she and Tristan—who also share daughter True Thompson, 4—welcomed their second child together via surrogate.

The rep for the reality star confirmed last month that True’s older sibling was “conceived in November.” This was one month after it was announced that True was pregnant with a baby. Maralee Nickels. (Tristan is also dad to Prince5. With ex Jordan Craig.)
