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.

"He will be a great dad, because he's an incredible dad with his other two children," Vongsvirates told RadarOnline.com last month.
