Jenna Dewan coos over newborn son Callum and gives him a back rub as they snuggle up together

She welcomed her son Callum into the world four weeks ago.

And Jenna Dewan cooed over the newborn in some new Insta Stories footage posted by her fiance Steve Kazee, Callum’s father.

Jenna, 39, lay down next to her infant and gave him a back rub – in a video Steve cheekily set to the fanfare from Richard Strauss’ Also sprach Zarathustra.

Although it was originally written in the 19th century, the tune became iconic in pop culture when Stanley Kubrick used it in his 1968 sci-fi movie 2001: A Space Odyssey.

Steve’s use of the music in the baby video was likely related to the fact that the last shot of 2001: A Space Odyssey shows a giant fetus floating in outer space.

Jenna announced the arrival of her new baby with a heart-melting black and white Instagram snap of her holding Callum close.

‘And just like that, our hearts exploded into all of eternity and beyond,’ she wrote. ‘Welcome to the world you little angel! Callum Michael Rebel Kazee 3/6/20.’

Last Thursday she posted an Instagram clip of Steve cradling Callum and kissing his forehead while she sang sweetly to the infant.

She and Steve began dating in 2018 and got engaged last month when he surprised her with a proposal at her baby shower.

Jenna also shares her six-year-old daughter Everly with her ex-husband Channing Tatum, whom she announced her split from in April 2018.

The proud mother told People that after Callum was born Everly ‘came to the hospital and it was adorable. She nuzzled him, she cuddled with him. She kept talking in a little baby voice and she was showing him pictures.’

Jenna shared: ‘She always wants to hold Callum. I don’t push him on her, but she’s been so excited and very loving towards him and open and cuddly. She keeps asking me when she can share a room with him.’
