Brandon Jenner's mum has shared the adorable first photo of his newborn twins.

The reality TV star and his wife, Cayley Stoker, are thought to have welcomed their baby boys on February 19. Jenner is also the father of four-year-old Eva, whom he shares with his ex-wife Leah. And taking to Instagram on Wednesday, Jenner's mum Linda Thaompson shared the first photo of the newborns - and revealed that his daughter, Eva, is already "the BEST big sister." “@caylita_ @brandonjenner are the proud parents of two exceptionally beautiful fraternal twin boys," she wrote. “Bo Thompson Jenner & Sam Stoker Jenner – already snuggling with their La La almost every day! Feeling so blessed as a family – with Eva being the BEST big sister imaginable! #twinboys #lala.” The 38-year-old revealed that he and Stoker had tied the knot last month, as he shared a sweet birthday tribute. "Happy Birthday to my beautiful wife, Cayley. I have discovered a whole new level of happiness because of you," he said, as he posted a series of photos from their relationship. "You are smart, kind, funny, driven, caring and super pregnant at the moment with our twin babies!! I will forever cherish what we have together and am so looking forward to celebrating every one of your birthdays with you from here on out. "Eva, Onyx and I are so unbelievably lucky to have you in our lives. Thank you a trillion times over for loving me the way you do."
