The National Treasure star weds Riko Shibata in Las Vegas. Nicolas, 56, and Riko, 26, tied the knot in Sin City's Wynn hotel on a date chosen to honour his late father's birthday. While the groom wore a Tom Ford tux, his bride wore a handmade Japanese bridal kimono. This marks the star's fifth marriage. Back in August, Nicolas announced he got engaged to Riko, but said the coronavirus pandemic prevented him from proposing in person. As he described on Marc Coppola's radio show, "She went back to Japan, and I haven't seen her for six months. We're really happy together and we're really excited to spend our time together so I just said, ‘I wanna marry you,' and we got engaged on FaceTime." The actor said he popped the question with a black diamond ring and mailed it to her. Nicolas was hopeful they'd exchange vows in a "really beautiful Shinto wedding", but plans obviously changed for the newly married couple.
