While posing for pics on the carpet, Tiësto cradled his wife's stomach and excitedly crouched down to draw attention to Annika's bump while she lovingly looked on.
The Dutch DJ was dressed in a black and gold floral print suit by Dolce and Gabbana, while Annika opted for an off-the-shoulder black, lace gown from the Italian design house. The dress featured a corset top and sheer details through the bodice and bottom half of the skirt.
On Monday, Tiësto, confirmed the happy news on his Instagram account writing, "I am having another baby with the love of my life ❤️."
He shared an adorable boomerang kissing his wife's stomach, as well as some photos from their night out in Las Vegas for Sunday's show.
