A man. And just as sweet. And caring, and kind, and intelligent…a beautiful future ahead.” Glanville also shared a photo of herself and Mason together. “You may legally be an adult now but you’ll always be my baby boy,” she wrote.

In February, she posted a photo with Jake and wrote, “This love of my life is taller than me now and possibly sassier??? I am so blessed ??#he keeps me on my toes??? .” Cibrian also shows a lot of love for Jake on social media. On his 13th birthday last April, the actor shared a photo of himself and Jake at the beach. “Happy Birthday, Jake!! ??You are truly an incredible young man,” he wrote. During an interview with Refinery 29 in 2017, Rimes talked about celebrating Stepmother’s Day, which is the Sunday after Mother’s Day, with Cibrian and his kids. “We go to dinner and do the whole thing,” she explained. “I love the fact that there is a stepmom’s day and an option [for stepparents to celebrate].” Rimes and Cibrian haven’t had any kids together, but Rimes feels like another mother to Mason and Jake. And it’s an experience that’s enriched her life. “It’s been really rewarding to see them grow up, and know that I have a part in that,” she said. “That responsibility, to help raise kids, it’s something that hits you really hard. It was something I was up for the challenge of. They bring so much joy to my life.” Like Cibrian and Glanville, Rimes also made an Instagram tribute to Mason on his recent birthday.“You are ridiculously handsome and as witty as they come, but most of all, it’s your massive heart that inspires me the most,” she wrote. “It’s an honor and a blessing to be your stepmom.” “He’s [Cibrian] gonna be in my life forever,” Glanville told Entertainment Tonight in 2015. “We’re raising two little boys together, and I think that ultimately, we put them first.” The reality star said that she and Cibrian have had their fair share of fights about “parenting styles.” But she’s grateful that her kids have a dad and stepmom who love them. “I would die for them, I would do anything for my children,” she added. The family weathered tougher times when the adults were not getting along. In 2009, when Rimes and Cibrian’s relationship became public, Glanville told US Weekly that Rimes was a “stalker,” who needed to leave Cibrian alone. A few months after that, Glanville released a statement about her breakup that included the phrase, “Eddie and LeAnn deserve each other.” However, Glanville told ET in April that she’s now in a good place with both Rimes and her ex. “This took time and 10 years,” she explained. “And I think that LeAnn grew up a lot, and I know that I’ve grown a lot. We just, we’ve grown up. We’re not little brats anymore…Honestly, there’s no weirdness, there’s no awkwardness. The kids are super happy when we’re all together and it’s finally good.” RELATED: See Sean Penn and Robin Wright’s Kids All Grown Up.
