Serena Williams has proven once again that she's a boss both on the court and off.
The tennis ace posted a picture of herself as Supergirl, along with a caption that explains how she tackled a mugger who took her phone.
Meanwhile, Heidi Klum won the title of Halloween Queen at the weekend.
The costume legend, who dressed as an old woman last year, sat through nine hours of prosthetics and makeup to transform herself into the cartoon icon, Jessica Rabbit.
Her star-studded bash saw Gigi Hadid as Sandy from Grease and Jennifer Lopez as the best looking skeleton you could imagine. Elsewhere, Kim Kardashian went as a parody of herself and Anne Hathaway turned into your favourite new emoji.
