Ashly Schwan looks as graceful as any swan in her hottest shots … and, we’ve compiled them all to commemorate her 28th birthday.

The YouTuber celebrated her milestone birthday Wednesday … and, while we don’t know exactly what she did, there’s a good chance she threw on one of her many bikinis — sizzling a couple months before summer is scheduled to begin.

Check out this pic of Ashly leaning forward … taking a selfie in the mirror while her chest is barely concealed in a frilly pink bikini top.

And, no matter the angle — like this one where Ashly’s backside takes center stage — Schwan has proven she’s always serving looks … even while navigating the rocky ocean.

So, happy birthday, Ashly … here’s to another year of bringing the heat!
