Olivia Culpo, Devon Windsor enjoy girls’ night out filled with ‘extra extra’ dirty martinis after F1 Miami Grand Prix

Olivia Culpo and Devon Windsor hit the town after watching the Formula 1 Miami Grand Prix Sunday.

The models dined at new hotspot Casadonna alongside two other female friends and Windsor’s husband, Johnny Barbara, the only male in the group. We’re told Culpo, whose fiancé Christian McCaffrey wasn’t with the group, ordered an “extra extra dirty martini” with regular olives — not bleu-cheese stuffed — for her drink of the night.

“They were so engaged in conversation. Everyone at the table was laughing and having a great time debating the menu, wondering if they should order bolognese,” an insider tells Page Six exclusively.

Although McCaffrey didn’t make an appearance, our eyewitness noted Culpo, 31, dressed in a bridal-white dress and white heels, which she accessorized with her “huge” diamond engagement ring. The Victoria’s Secret model, 30, opted for a stunning high-neck, long-sleeved backless dress for the night out.

“Olivia kept gushing about Devon and Johnny as a couple and even reminisced about being there the night [the couple] met,” our eyewitness says.

“It was just a really fun group having a good time together, but poor Johnny was the only dude!”

Earlier in the day, Miss Universe 2012 wore a high-neck red minidress to watch Lando Norris win the big race. Though her striking outfits stole the show, Culpo’s smaller lips were also noticeable in light of her decision to dissolve her filler ahead of her wedding to the San Francisco 49ers running back.

The former pageant queen told her Instagram last week that she’s “really happy the way they look now”

“Debating filling again but might just keep like this for the wedding,” she wrote, adding a question box asking if she should get them re-done.

Culpo previously commented on her cosmetic surgery History, revealing that she has “never had plastic surgery” nor buccal fat removal, but admitted to dabbling with Botox, fillers and lash lifts.
