Brandon Jenner's New Girlfriend Is Pregnant with Twins, Weeks After Finalizing Leah Jenner Divorce

Brandon Jenner and his new girlfriend, Cayley Stoker, have just announced that they're expecting twins.

"We are at 12 weeks now, so near the end of the first trimester," Caitlyn Jenner's second oldest son told PEOPLE on Tuesday. "We're madly in love and we are very excited about this!"

The 38-year-old musician and his 36-year-old ex-wife, Leah Jenner, who both appeared on episodes of "Keeping Up with the Kardashians," announced their separation on Instagram on September 10, 2018. Their divorce became finalized on July 15, 2019.

But Brandon maintains he and Leah have been able to maintain a positive relationship since the split, especially for their 3-year-old daughter, Eva James Jenner.

"Leah and I split up in a really beautiful way, and I think we handled it in the best way possible," he explained. "It was a process, and it took some time to finalize. And now that Leah and I have moved on, I am starting a family with Cayley, and I'm so happy about it."

According to Brandon, all three parental figures sat down with Eva to let her know she was going to be a big sister.

"We told her together," he said. "Leah, Cayley and I sat down with her and told her what was happening, and she was very excited and happy. She's super excited to be a big sister."

Brandon and Leah were together for 14 years and spent six of those married.

"It is with love in our hearts that we feel it's time to share some personal news with you all," they wrote in the joint statement they shared on Instagram last year. "After celebrating fourteen beautiful years together, we have lovingly come to a decision to end the romantic aspect of our relationship."

"We are deeply proud of the life we've cultivated together and are truly grateful for the bond of friendship we hold and cherish today," they continued. "It is stronger than ever. Even though we have chosen to separate as a couple, we still love one another very, very much and remain a major part of each other's lives -- as best friends, family and loving parents to our daughter."

"There has been no lying or cheating or fighting that prompted this change, just an expansion of our individual evolution which has inspired us to support each other in a new way," the statement went on. "We are still, very much, a loving family and are bonded by a deep connection that is rooted in love."

The statement concluded: "Here we openly share our truth with you all and, respectfully, we won't be commenting further so anything that might state the contrary of this message, would, undoubtedly, be a fabrication. Thank you for your love and support and big love back to you guys!"

The two tied the knot on May 31, 2012. They welcomed Eva, their only child, in 2015.
