The 55-year-old actress gave birth to daughter Frida last month and Brigitte says she and her husband, Italian model Mattia Dessi, feel blessed with the new addition.

She told PEOPLE: "It's the best time in my life, with my adorable little Frida, my wonderful husband and four beautiful grown-up sons.

"Life is amazing, you only get one, so take good care of it, and live it to the fullest."

Brigitte - who was married to Sylvester Stallone from 1985-1987 - shocked the world when she announced in May that she was pregnant with her fifth child.

Before falling pregnant with Frida, the star - who has been married five times - already had sons 34-year-old Julian, with first husband Kasper Winding, 28-year-old Killian with Mark Gastineau, and 25-year-old Douglas and 23-year-old Raoul Jr., with fourth husband Raoul Mayer.

The 'Cobra' actress caused a stir on social media with her pregnancy announcement, with many fans calling her an "inspiration" for having another child later in her life.

Responding to one fan, Brigitte wrote: "Nobody has the rights to lead your own decision unless you allow them to do so. You're the only one in charge of yourself and your own happiness. Best of luck!"

Brigitte has been married to Mattia since 2006, but was previously wed to Kasper for a year from 1983 to 1984, before she enjoyed a two-year marriage to Stallone, followed by Sebastian Copeland in 1990 until 1992, and then Raoul from 1993 to 2005.

She announced her pregnancy news in two separate posts on Instagram in May, which showed off her burgeoning baby bump.

On one, she wrote: "family getting larger #me #family #brigittenielsen #babybump (sic)"

Whilst on the second she added: "happy time positive vibes #happyness #positivevibes (sic)"
