In the video, Axel - who is nearly four months old - can be seen walking (held up by a pair of adult hands of course!) and it's so cute.
You can watch the clip below:
Uploaded onto Perrie's Instagram Stories, little Axel can be seen wearing some very stylish red, Christmas tree socks and walking across what looks like a table while being held by an adult who is out of shot.
Set to the tune of Step Into Christmas by Elton John, little Axel looks so adorable as he tiptoes along the table.
In the background, there are four Christmas stockings, one reading 'Pez' and another 'Alex' in reference to Axel's dad, footballer Alex Oxlade-Chamberlain.
And fans are loving the cute clip, with one person writing on Twitter: "Axel’s ready to step into Christmas!"
While another said: "Perrie and Axel the cutest duo in the world."
And a third added: "Perrie trusts us enough to share axel’s 'first steps' with us."
Meanwhile a fourth said: "Baby axel on Perrie's story I am DYING FROM CUTENESS OMG."
"AXEL with his little socks I can’t!!! Perrie and Alex really made the cutest little man," said another.
Perrie and Alex welcomed their son in August, announcing on Instagram at the time: “Welcome to the world baby 21/08/21" before sharing a series of black and white snaps of the tot's tiny arms and legs.
The Little Mix star announced her pregnancy in May, revealing the happy news with an adorable photo alongside partner Alex.
Perrie welcomed her little one just days after bandmate Leigh-Anne Pinnock gave birth to twins. The band has recently announced they will be taking a break after their Confetti tour next year.
In a tweet, they announced: "We wanted to let you all know that after the Confetti tour in April/May next year we are going to be taking a break from Little Mix.
"It’s been 10 amazing years, a wonderful non-stop adventure, and we feel the time is right to take a break so we can recharge and work on some other projects. We can’t thank you enough for your love and never-ending support since the beginning. We love you all SO much."
They then assured fans: "We are not splitting up - Little Mix are here to stay. We have plans for more music, tours and performances in the future. We’ve made so many incredible memories with you all, and we can’t wait to make so many more."
