US Open champ Coco Gauff still has a massive grin on her face after winning the big tourney, but she won't be celebrating with a huge bash ... just a bunch of zzzz's.
The 19-year-old pro seemed to be in a great mood Monday, stepping out of her NYC hotel room just days after striking gold at this year's big event. Coco stopped to snap a pic with a fan while jumping in a waiting car with a Miles Morales plush in her hand.
Of course, Coco was asked about her post-win plans, but the only thing on her mind is heading home and climbing in bed for some sleep .
