and girlfriend Ramona Agruma shared updates from their first outing with new baby Royce Lillian following recent backlash from internet mums.
The pair excitedly uploaded snaps from the ‘baby’s first adventure’ on Sunday after announcing on Instagram.
Posing behind the baby girl’s stroller, the happy couple looked relaxed and casual in sweatpants, gym leggings, trainers and sunglasses.
Boasting blue skies and seaside views, the photos posted on the star’s Instagram story showed Rebel and Ramona doting over Royce, who was dressed in a pink ensemble with a heart emoji to match placed over her face to hide her identity.
The new family sat on the patio of the celebrity hotspot and dined on sushi while looking out over the Pacific Ocean.
Holding her ‘miracle’ daughter in her arms, the Pitch Perfect actress planted a kiss on her daughter’s head and shared it with her 11.3 million followers.
Recently coming under fire from mums on the internet for attending Paris Hilton’s party a few days after the arrival of their daughter, in comments allowing the new mother time to breathe.
‘Are mothers not allowed to let their hair down? Are mothers not allowed to take a break for their own self, their own soul?’ fans wrote in support for the star.
On seeing the star enjoying herself on Santa Monica Pier, angry nay-sayers were quick to criticise and shame her for leaving Royce at home.
One questioned: ‘Ummm sorry?!? Didn’t you just get given a baby this week. So confused right now. This is the most important time to bond with your baby, not party.’
The trip to the coastal eatery came after Ramona planned a baby shower for her other half, an event that Rebel explained ‘went above and beyond to make it a special day’ in a chat with People.
Since welcoming the small human into their lives, the sustainable fashion entrepreneur and founder of Lemon Ve Limon opened up about the ‘life-changing’ experience of becoming a mother alongside Rebel.
Appearing on Australia’s The Morning Show, Ramona revealed: ‘It’s like you start thinking about someone else instead of yourself, priorities change.
‘When you think, “Aw, I wish I would go have a massage” or something, instead you’re like, “No, I just want to spend time with her and be at home.”’
Rebel and Ramona went Instagram official in June when the actress shared a post in honour of her new leading lady.
Underneath a smiling selfie, the Senior Year actress wrote: ‘I thought I was searching for a Disney Prince… but maybe what I really needed all this time was a Disney Princess #loveislove,’ followed by a rainbow and heart emoji.
