The McBusted singer uploaded a photo of his wife dressed in the exact same colours as their son Buzz' baby beaker.
With the green handles very much similar to the green sleeves on her top and a blue body, we can totally see the resemblance.
Fletcher simply captioned the photo: "When your wife dresses as a beaker...".
Giovanna's beaker-like top also shows a hint of her baby bump, but the couple are yet to reveal how far along she is.
This isn't the first time the Mickey Mouse/beaker top has made an appearance.
Fletcher uploaded a hilarious video of his wife dancing on 9 September, shortly after announcing their baby news.
The couple married in May 2012 and their son Buzz was born in March 2014.
Fletcher also recently shared a close up photo of his wife's "baby lump" on Instagram, showing Giovanna's belly in a tight grey top.
