Jennifer Lopez and Alex Rodriguez enjoyed a couple’s night out celebrating the launch of Guess’ new spring 2018 campaign, which stars Lopez as the latest face of the brand.

Lopez wore her hair in a romantic, old Hollywood up-do featuring plenty of curls and sported a baby blue midi dress from the Marciano collection underneath a dramatic, matching fur coat. The look was topped off with sparkly Christian Louboutin pumps and plenty of diamond jewels, including $30,000 diamond earrings by Yeprem. Rodriguez complemented his girlfriend’s outfit in a deep blue velvet jacket and crisp white button-down shirt.

“Sometimes I’ll say, ‘Do you like this or do you like this better?'” Lopez told PEOPLE at the event in L.A. Wednesday night. “He’s like, ‘Is this a trick question? I like whatever you want to wear!’ Yeah, but we help each other out when we can.”

The Guess Spring 2018 launch party happened the same day that supermodel Kate Upton called out the brand’s co-founder and creative director Paul Marciano for allegedly using his power to harass women.

“It’s disappointing that such an iconic women’s brand @GUESS is still empowering Paul Marciano as their creative director #metoo,” Upton tweeted.

Upton followed up her tweet with an Instagram post which she captioned, “He shouldn’t be allowed to use his power in the industry to sexually and emotionally harass women #metoo.”

The 25-year-old model has starred in a number of Guess advertisements, but did not clarify whether she had been victimized by Marciano in the past.

A rep for Guess and Marciano did not respond to PEOPLE’s request for comment.

Marciano spoke to TMZ Thursday about Upton’s claims, denying that he ever touched her.

“If she has a claim, there’s one place to tell the truth and that’s in court or to the police,” he told the site, adding the he feels Upton has bad blood after Guess cut ties with her for showing up to set “looking terrible.”

On Thursday, Lopez released a statement to PEOPLE, regarding her continued stance on eradicating sexual harassment in all work places.

“My position on these issues is well known, as I have been very vocal about them,” she shared. “I do not condone any acts of sexual harassment, violation, or misconduct. Any accusations should be fully and thoroughly investigated. I will continue to support our rights as women. “
