Britney Spears and Sam Asghari are not the only ones enthusiastic about the impending arrival of their baby. Spears' sons, Sean and Jayden, 16 and 15, are excited to be big brothers as well.

Since the conservatorship ended, many in the lives of Britney Spears were talked about, even her exes apart from her friends and family. However, there's an obvious lack of attention paid to her son's feelings, especially about her relationship to Sam.

This new development just shows how happy Sean and Jayden are for their mother, not just for the ending of her conservatorship battle, relationship with Sam Asghari, but also with this next chapter of her life.

In an exclusive interview with Hollywood Life, a close friend of the 40-year-old singer said the boys were the first to learn about her pregnancy, and the entire family is thrilled for them to become big brothers.

There's no denying how much Britney struggled in raising these two kids at a time when people are generally unkind to single mothers, and at a time when the star was still locked in her conservatorship.

"With Sean and Jayden, she was stripped of the right to have this experience. In the first part of their lives, she was still focused on her career and had very little time for herself. When they were 2-3, she was placed into conservatorship and she never got to have the firsts that many mothers do with their kids because, after that, she always had to have someone else present, or have monitored visitation," sources said.

This is why the new baby is going to experience a very different Britney Spears. The icon is going to make sure of it. "Britney is so thankful that she finally gets to have the experience of raising a baby that she has always dreamt of her whole life. There was a point where she didn't think this would ever happen," the sources added.

Kevin Federline has custody of Britney's two children, Sean and Jayden. As soon as the news of Kevin's pregnancy broke, he sent his best wishes to E! News via his attorney. He expressed how happy he is for her.

Naturally, Britney Spears' fiance Sam is the most ecstatic of them all. The 28-year-old said fatherhood is something he "always looked forward to," so there is no chance that he would taking this "lightly."
