SI Swimsuit's newest rookie Ellie Thumann is clearly ready for summer, and we can’t get enough of the YouTuber’s sunny vibes.

The 21-year-old model and influencer posted a TikTok on Wednesday of herself sipping an iced coffee in a convertible with the sun shining on her face.

“A few more months till it’s best time of year again,” the on-screen text read.

Thumann used an audio clip from the romantic-drama series The Summer I Turned Pretty.

“For me, it was almost like winter didn’t count. Summer was what mattered,” the voiceover said. “My whole life was measured in summers. Like, I don’t really begin living until June, until I’m at that beach in that house.”

Thumann solidified the laid-back, casual vibes with an adorable athleisure set from Alo. She wore the brand’s Airbrush Streamlined Bra Tank ($64) in Infinity Blue/Black and a pair of athletic bottoms in the same light blue color.

“Living your best life we love to see it,” a fan wrote in the comments.

“105 days to be exact hehe🌊✨,” another person added.

“I love ur vibe 🦋🏝️🏝️🏝️,” someone else gushed.

Other followers were quick to point out what looked like a man’s arm clad in a white T-shirt in the corner of the video frame.

“ok ellie i see a boy . good for you !👀,” one person said.

“soft launch?” another individual quipped.
