Vongsvirates, 34, exclusively told RadarOnline.com last month that the two have been dating for five years, but have kept their relationship extremely private. In June, however, Us reported Wilson, 49, took a paternity test to make sure Vongsvirates was carrying his baby.
Before welcoming their daughter, Vongsvirates shared a snap of her pregnant belly on Instagram, looking excited for the journey ahead.
"Say hello to Lyla. 3 months to go!" she captioned the sweet photo.
As Radar readers know, Lyla will be the actor's first daughter, but third child, as he is already a father to son Robert Ford, 7, with ex Jade Duell and Finn Wilson, 4, with ex Caroline Lindqvist.
"He will be a great dad, because he's an incredible dad with his other two children," Vongsvirates told Radar last month.
