Rosamund Pike's son came out "the most chilled little guy".
The actress has 14-month-old Solo with her boyfriend Robie Uniacke.
The tot's unusual name matches up to his relaxed personality according to his proud mom.
"It's the notion of freedom," she revealed to British magazine OK! when asked the reason behind the moniker.
"It's solo travel, solo flight, it's that independent spirit and that's what really matters to me in life. He came out the most chilled little guy. He's really mellow."
Rosamund first rose to fame when she played Bond girl Miranda Frost in 2002 flick Die Another Day.
Now aged 34, she feels better than ever about her life.
"In some ways I feel younger than I did in my early 20s and that's weird, isn't it?" she marvelled.
"I suppose it's the freedom that comes from not caring what other people think."
Rosamund also revealed that having Solo has helped her relax.
She's no longer so hard on herself when she makes "mistakes".
While he may be yet to turn two, the star already knows she wouldn't mind him following in her career footsteps.
"I'd be delighted if it's what he wants to be, if he is good," she smiled.
"But it's hard to be in this profession and if it's what you really want to do and you're not good enough, then that's really tough."
