Her tresses were styled in soft waves and she sported a rich palette of make-up.

Norman wore a black suit and bow tie as he held hands with his love. 

Norman and Diane met when they co-starred in the 2015 movie Sky and began dating the following year.

In her children's book, Diane describes how she came to embrace her own name and how she and Norman chose their daughter's moniker.

Diane told People that the little girl's nicknames range from 'Noonoo' to 'Neenee'.

After welcoming Nova, star said she was surprised by 'how much I love it. I wanted to be a mom and I was sure I was going to like it, but just the magnitude of wanting to be there every second, not missing a thing.'

She told People that it has been 'wonderful to rediscover firsts.
