The Big Momma's House star welcomed her second child, a son named Kez, with her basketball player boyfriend Ime Udoka in November (11) and Long believes motherhood has given her a new lease of life.
She tells TheUrbanDaily.com, "I am the happiest that I've been probably in my life.
"Baby Kez Sunday has given me a bit of a rebirth and it's really nice because I'm able to look at life through his eyes. You have to pay attention to the smallest thing from the birds chirping to the dog barking across the street. These are the things that make the world go around today. When you look at life in its simplest form, stress and worry isn't (sic) the cornerstones of your life. Experiencing life through that lens is refreshing."
Long has been on a career break since wrapping her last project, a 2011 drama called Mooz-lum, and she admits she's in no rush to return to work - but her eldest son Massai has other ideas for his mum.
She says, "My 11-year-old is running the show. He's like 'Mum, when are you making another movie?' I'm a true believer that good work finds you and I hope that I've established enough of a career of myself that when they want Nia Long they'll find Nia Long."
Massai is Long's child from a previous relationship with actor Massai Z. Dorsey.
The Best Man star has followed in Demi Moore and Britney Spears' daring footsteps by showing off her pregnant figure for the November (11) cover of the black women's publication.
In the accompanying interview, Long insists she has no issues about becoming a parent for the second time at the age of 41, telling Ebony, "Society tells us ‘Get married before 30…’ I think if we just take our time as women, and do what comes natural to us and for us, we would make fewer mistakes."
The magazine will hit newsstands later this month (Oct11), coinciding with Long's due date.
The actress confirmed reports she was expecting her basketball player boyfriend Ime Udoka's baby in June (11). The tot will be a little brother or sister for Long's 11-year-old son Massai, from her previous romance with actor Massai Z. Dorsey.
