Girardi is well known for her season 14 victory on The Bachelor, where she accepted the final rose from Dallas-based pilot Jake Pavelka before their engagement ended over the phone three months later.
“It’s been a struggle thinking about my relationship and going in front of the camera and shooting,” Pavelka told PEOPLE following their split, around the time he was filming for Lifetime’s Drop Dead Diva.
He added, “It was a difficult conversation on the phone. But the relationship was headed in that direction.”
Though Girardi has remained largely out of the spotlight the past few years, she famously dated former Bachelorette contestant Kasey Kahl while appearing on Bachelor Pad. The two called it quits in late 2011.
The twins on the way are the first children for Girardi.
