They celebrated the birth of their first son together, Lars Gerard Gibson, at the start of the year.
And Mel Gibson and his girlfriend Rosalind Ross looked the picture of contentment as they strolled through Los Angeles on Saturday.
Former horserider turned screenwriter Rosalind wore a grey and white striped top pulled up at the sleeves. She looked super cool in a pair of dark sunglasses to match her jet black locks, which tumbled over the loose-fitting item. Rosalind also went for snug-fitting leggings to show off her slender pins and a pair of casual Converse-style shoes.
Gibson, who has nine children by three different women, wore a bulky black baseball cap and blue jeans. The Braveheart actor also opted for a tricolour polo with a pair of sunglasses tucked in front of a silver necklace. A pair of walking boots shielded his feet as he beat along the sunny pavement hand-in-hand with his girlfriend.
Lars Gerard Gibson was born on January 20, and weighed in at 5 lbs. 5 oz.
A source told People: 'They’re thrilled and Lars is adorable. Their family is all around them and Mel is over the moon. They’re home and everybody is healthy and happy!'
The director has seven children with ex-wife Robyn Moore: Hannah, 36, twin boys Christian and Edward, 34, William, 31, Louis, 28, Milo, 26, and Thomas, 17. He also has a six-year-old daughter, Lucia, with former girlfriend Oksana Grigorieva.
During an interview on the Golden Globes red carpet, the actor told Richard Wilkins he feels fit to be a father again. At the time, he admitted that he didn't have a name picked out for his child, choosing to keep the sex of the baby a secret. He joked with the Today reporter that he some of the ideas included 'Regis' and 'Remis,' which are male names and suggested the child was a boy.
They were said to be 'so excited' and it was claimed that 'The last two years [had] been some of his happiest years [Mel has] ever had.'
