The couple has started planning their 2021 nuptials but they aren't going to make it a huge affair because of the ongoing coronavirus pandemic.

"We don’t want to have a super big wedding, but our small wedding is probably gonna be someone else’s big wedding, so we’ll see how things go," said the star. "But we’re planning on doing it far enough out to where hopefully the pandemic settles down a little."

Meanwhile, Young confirmed she's picked out her rehearsal and wedding dress. Young said that Galia Lahav designed the gown, which she's already chosen.
