Jenny Mollen and Jason Biggs
Encore! Encore! After Jason Biggs eloped with actress Jenny Mollen in a "very private ceremony
" in April, the two are now planning to exchange vows again – this time, in front of family and friends, his American Pie
costar Alyson Hannigan tells PEOPLE.
"They're going to have a proper wedding in Napa," Hannigan revealed at a New York screening of her hit CBS show How I Met Your Mother
. "I have my invitation, but I don't know if it's going to work out, traveling-wise. I have to figure out the dates."
Still, she says, "Hopefully I'll get to go to the wedding and really celebrate then."
When it came to Hannigan's learning that Biggs had tied the knot in the first place, "I actually found out through a text message," she says. "I was like, this is a weird world when you're finding out your friend eloped via text."
The former Buffy, the Vampire Slayer
star – also remembered for the "band camp" conversation with Biggs's Pie
character, Jim – encouraged the newlyweds' relationship from the start. She was already a friend to both Mollen and Biggs.
"After she met him, she called me. She was like, 'What do you think about him?' " Hannigan recalls. "So, of course, I raved about him."
Married nearly five years herself – to actor Alexis Denisof – Hannigan also offered some advice to her pals: "Just adore each other. Communication is key. And lots of hugs and kisses."
