It’s honestly hard to tell whether the sun or Millie Bobby Brown was hotter in her latest bikini snaps … so we’ll have to call it a draw.

The “Stranger Things” star posted some pics of a recent visit to the Beach today … and needless to say, MBB looked pure fire.

Between her toned body and fantastic tan … Millie didn’t have to say much … and she didn’t! The caption for the three pics was simply … “☀️🌊🐚.”

Prior to the sizzling snaps … MBB posted a series of BTS pictures from her work in the upcoming “Enola Holmes 3,” which apparently has wrapped production with MBB captioning her pictures, “case closed.”
