Fans missed out again this week as the expectant star turned up to see her manager Simon Fuller get a star on the Hollywood Walk of Fame.
The singer-turned-fashion designer looked elegant in a black silk draped dress from her own collection.
But with gathers at the waist, the design obscured her bump from onlookers.
And the nude-hued bag she held over her middle was a further barrier.
With roughly six weeks to go till the arrival of her little girl, the former pop star shows no sign of abandoning her hallmark heels.
She chose a pair of vertiginous Louboutins to attend the ceremony with her eldest son Brooklyn.
Showing no qualms about wearing a figure hugging dress, however, was Jennifer Lopez.
The American Idol judge showed off her bombshell curves in a teal Zac Posen gown. She attended the star unveiling with husband Marc Anthony.
Also turning out to fete American Idol creator Simon was former winner Carrie Underwood.
The man of the moment said it was strange being in the spotlight for once.
"You have no idea how bizarre, strange, awkward and many other words I feel right now because I'm usually sitting over there, or back there, or up there, and very rarely find myself in the spotlight," said Simon.
Then, he quipped: "Actually it's great. I think I should do my own reality show."
