Sylvester Stallone's 54-year-old ex-wife shared surprising photo of her baby bump

Brigitte Nielsen announced on Instagram that she is expecting her fifth child. Nielsen was married to Sylvester Stallone for two years in the eighties.

Earlier this week, she shared a photo of herself reclining on a chair, wearing a white dress and holding her pregnant belly. She simply wrote 'family getting bigger' in the caption.

Nielsen added the heart emoji and the hashtags 'family' and 'baby bump.' Three days later, she added another photo and wrote: 'happy time [heart emoji] positive vibes,'

According to Page Six, Nielsen has four sons ranging in ages from 23 to 34. She was married to Kasper Winding from 1983 until 1984, and they had one son, Julian.

She married Stallone in 1985, but they parted ways nineteen months later. They don't have any children together, and Nielsen started dating Mark Gastineau the following year.

The couple broke off the engagement soon after, but share one son, Killian, who was born in 1989. She was then married to Sebastian Copeland from 1990 until 1992.

She married her fourth husband, Raoul Meyer, in 1993. They were together for 12 years, before filing for divorce due to irreconcilable differences.

They have two sons together, 25-year-old Douglas Aaron, and 23-year-old Raoul Jr. Nielsen is currently married to Mattia Dessi, and the couple has settled down in Palm Springs

Nielsen landed her first role in 1985 in Red Sonja, alongside Arnold Schwarzenegger. That same year she also appeared in Rocky IV, alongside Stallone.

Her career spans more than three decades, and she has 39 acting credits to her name. She also has her own Danish talk show, Gitte Talks, on Kanal4.

Fans of Nielsen can look forward to her upcoming films. Adi Shankar's Gods and Secrets is completed and will be released later this year.

She was also cast as Ezilda in the film The Experience. It is currently in post-production. The drama follows two girls who are 'tested by love, money, and experiences beyond their perceived realm of existence.'
