Kate Upton shopping for wedding gowns in Barcelona

Actress and model Kate Upton jetted off to Spain to find a wedding dress last week (ends28Apr17).

The Other Woman star, who is engaged to baseball hero Justin Verlander, was spotted at the Pronovias 2018 bridal show in Barcelona on Friday, and told Entertainment Tonight she may rock a series of gowns on her big day.

"I like it all, so maybe (I'll have) multiple dresses," Upton told the outlet. "Maybe a nice long sleeve, and then also the big tulle one."

Kate also revealed her gown will be sexy and she's not afraid to flash a lot of flesh when she exchanges vows with Justin, adding, "I think that I always like to add a little flair of sexuality to any outfit I'm wearing (and) my grandparents get Sports Illustrated... they've seen it."

The stunner became engaged to the Detriot Tigers pitcher last year (16), and showed off her reported Anita Ko $1 million (GBP780,000) engagement ring at last year's (May16) Met Gala.

She tells ET the proposal was a truly magical moment: "I was completely surprised," she gushed. "There was this moment before he proposed (when) I was like, 'Is he? No', and I just kept enjoying dinner.

"He did amazing. He knew that I would be wearing it every single day, so he did all of this research behind the ring, and he almost had, like, a mood board set out that he was looking at and what he thought I would like."

And her husband-to-be had to be careful when it came to informing Kate's parents of his plans, because they're terrible when it comes to keeping secrets.

"He doesn't trust my parents with secrets because they told me once what he was getting me for my birthday, so he only told them two days before he asked me," she chuckled.

The Sports Illustrated favorite is not giving up wedding day secrets just yet, but she told ET she's planning "a destination wedding", adding, "We don't really get the opportunity to go on a lot of vacations together because of how long the baseball season is, and how busy we both are, so I think that what we want for our wedding (is to) have all of our closest friends and families go on an extended vacation together."
