The 33-year-old actress and her musician beau debuted their baby girl for the first time over the weekend.
However, the married couple's new little bundle of joy was all wrapped up and resting in her baby capsule as her new parents and three-year-old sister Naleigh stepped out to celebrate Mother's Day.

The former Grey's Anatomy star and husband Josh adopted Naleigh from South Korea in 2009 when she was 10-months-old.
Significant moments: Katherine and her friend affectionately exchanged whispers
The actress said her daughter’s initial rejection almost broke her heart as she struggled to cope.
She said she threw herself into work but found being apart from Naleigh only made the situation worse.
'At first I blamed myself and thought I was a bad mother. It took a while before I could admit to myself that the lack of trust had nothing to do with me,' she said.
The actress expected to bond with her daughter immediately - but was upset when she was rejected and described the months that followed as the 'hardest time in my life.'
'I fought incredibly hard for my daughter to accept me as mother. Her rejection almost broke my heart,' she told a German newspaper.
Katherine said she immersed herself in work filming The Ugly Truth with Gerard Butler and Killers with Ashton Kutcher.
But being on a film set away from her family only made the problem worse.
'When I realized that, I immediately cut back on work,' she said.
Katherine said when Naleigh bonded with her husband she felt a failure as a mother.
Now two years since the adoption Katherine said they have a tight bond.
'My sister Meg is Korean and my parents adopted her three years before I was born,' Katherine said in an magazine interview.
'I wanted my own family to resemble the one I came from, so I always knew I wanted to adopt from Korea. We have talked about having biological children as well, but we decided to adopt first.'
