Brian Austin Green shared a rare snap of Sharna Burgess with their blended family to mark Mother's Day on Sunday.
The 90210 actor, 50, who shares three sons with ex-wife Megan Fox and one son with Burgess, 38, as well as eldest son Kassius, 22, with ex Vanessa Marcil, posted a cute snap showing his youngest four children snuggled up with his fiancee.
In the snap, his and Fox's sons Noah, 11, Bodhi, 10 and Journey, seven, as well as the couple's son Zane, 23 months laid on a bed embracing as they watched a film.
Brian wrote: ;You stepped into this world (which could not have been farther from the one you knew) and have become the rock of this family.
'You are an incredible mother and fiancé and we all love you to death. Happy Mother’s Day baby.'

Burgess responded: 'Oh my gosh. The best thing that ever happened to me was you and those babies right there.
'You were all always a part of my future and my story and I wouldn’t have it any other way. I am the luckiest, and I love you all so much. Thank you for making me a mama.'
Last month Green insisted that he has always made his children his 'number one' priority in life.
Asked about his approach to co-parenting, the actor – who recently reunited with Tori Spelling and Jason Priestly – stated: 'The number one is always make sure that everything is centered around the experience of the kids.'
The Beverly Hills, 90210 star also opened up about several other important lessons about co-parenting he had learned over the past few years.
He explained: 'The person that you were with that you're now separated from, you guys are separated for a reason, because you didn't get along.'
Green went on to state that separated parents should prioritize the well-being of their children despite the end of their romantic relationship.
He said: 'You can't expect to then get along after the fact in raising your kids. So, you have to decide, "OK, it's not about us getting along anymore. It's about us co-parenting, which is a totally different situation."'
Green began dating Fox in 2004 when she was 18 and he was 30 – they wed in 2010 and split in 2020

Fox moved on quickly with 'twin flame' Mgk but the pair have now ended their engagement
The performer also admitted that separation inevitably makes impacts on children and that parents should navigate their splits with care.
'People make a mistake of thinking that they're gonna do things so the separation doesn't affect the kids and…of course it's gonna affect the kids. The only choice you have is how it affects the kids,' he said.
Green and Fox began dating in 2004 after they met on the set of the sitcom series Hope & Faith.
The performers maintained an on-off marriage for several years, and their union was formally dissolved in 2021.
The Jennifer's Body star moved on with Machine Gun Kelly, although rumors about a potential breakup for the pair began to swirl earlier this year.
Green started dating Sharna Burgess, who was his dancing partner for season 30 of Dancing With The Stars, in 2020.
