: best husband ever?
The Little Couple
star makes grooms everywhere want to step up their game in this exclusive clip from Tuesday night's episode, which shows Klein sweetly presenting wife Dr. Jennifer Arnold
with a gorgeous ring and then getting her permission to renew their vows the following day.
(Arnold, 39, looks momentarily panicked to be renewing their vows so soon, but not to worry – he's handled every little detail.)
"After all that we've been through, I love you more now than I have before," Klein, 39, told a beaming Arnold as he kneeled before her. "Let's let everybody know that it's just as good as it was day one."
Their April 27 vow renewal
on the beach in Galveston, Texas, is a happy reprieve from a tumultuous year for the diminutive duo. In late 2013, Arnold revealed she was battling a rare form of cancer
(now in remission
). The diagnosis came around the same time they adopted their second child, daughter Zoey
, 2, from India. They are also parents to son Will
, 3. Both children have forms of dwarfism.
Their two young children took part in the emotional seaside ceremony, which celebrated
the triumphs of this inspirational family.
"I have the most amazing, incredible husband ever," Arnold told the cameras shortly after Klein proposed again. "I'm feeling very loved right now, and very special."
