Camille Kostek dons $5000 Maria Lucia Hohan outfit at SI Swimsuit party in New York

Rob Gronkowski's girlfriend Camille Kostek was one of the more popular models in the Sports Illustrated Swimsuit issue in the 2010s. Now, she returns for its latest milestone edition.

On Saturday, the magazine hosted the first launch party for its 60th anniversary special. She showed up in a silver Maria Lucia Hohan silk gown that costs $5,089:

She and Gronkowski started dating in 2015, and save for a brief spell wherein they broke up, their relationship has mostly stood firm. She recently told Page Six:

"We’ve had our ups, we’ve had our downs, and we’ve been able to break up, do our thing and get back together and heal in different ways, and learn and grow through the years.”

Camille Kostek calls Tom Brady's Netflix roast "dream job" for Rob Gronkowski

If Camille Kostek is to be believed, Rob Gronkowski loved watching his former teammate get roasted.

Almost two weeks ago, Tom Brady sat onstage as multiple celebrities made jokes about him on Netflix. Among then was his former tight end, who punctuated an occasionally incoherent ramble by breaking a glass onstage, a reference to his partying antics.

Speaking to ET during SI Swim's 60th anniversary launch, she said:

“It was like a dream job for him. To just rip on all of his teammates and just be a class clown for everybody to watch. He is still laughing to this day reminiscing on the jokes. I think I memorized the roast now.”

In an earlier interview for Extra, Kostek also shared how Gronkowski's rehearsals influenced the jokes he shared:

“I heard him practicing and there was a lot of things where I was like, ‘That wasn’t in it,’ and then you hear him say right after he said that joke, ‘I just came up with that one right now.’”

She also discussed his reaction to her latest SI Swim shoot:

"Each year, I think he's getting like less excited because he's like, 'I know you're in the magazine and there's pictures of you. I see them all the time.'

"But he was like, 'That’s a good one, Camille.' We shot it at night, it's like a high-flash shot by a pool. He was like, ‘This is something like you’ve never done before... These are really cool that you didn’t shoot on a beach this year.’”

The SI Swim 60th Annoversary edition is currently available in stores, having been relased on Friday.
