Matthew & Camila McConaughey 'Howl at the Moon' with New Pantalones Tequila Cocktail at STK Steakhouse

Halloween may be over, but the full moon is still shining — and Matthew and Camila McConaughey are keeping the festive spirit alive with a brand-new photo and nationwide cocktail launch in partnership with Pantalones Organic Tequila and STK Steakhouse.

The couple was recently spotted celebrating the full moon — or as they call it, "howling at the moon" — the Pantalones way: pants-less, cocktail in hand, and all good vibes. The playful image is the latest in their signature "Official Tequila Of" campaign.

Coinciding with the launch, STK Steakhouse introduces the "Howl at the Moon" cocktail — a tequila-infused twist on the classic Espresso Martini — now available at all STK locations nationwide. The drink promises to kick off your night of partying your pantalones off in true McConaughey style.

For those who prefer to howl from home, Total Wine carries all the ingredients needed to shake up your own Pantalones Organic Tequila Espresso Martini, aptly named the "Alright, Alright, All Night."
