Comedian Amy Schumer took to the high seas on a boat to celebrate the special day, but didn't appear to be having the best time. "I'm a blast at sea," Schumer ironically captioned the Instagram pic.
Meanwhile, others stars opted to keep things more low-key for their observance of Memorial Day. Justin Bieber rocked a fedora and a white dinner jacket with no shirt over swim trunks while talking on his phone and standing at the edge of an infinity pool.
Blac Chyna also showed off some clothing, but was more interested in showing off some skin, when she rocked a super low-cut champagne gown during her Memorial Day festivities. Check out the video below for a look at the model's steamy, cleavage-baring style.
