Tennis icon Serena Williams in Zebra-Print dress During Pit Stop at Monaco Grand Prix

Future mother Serene Williams doesn't know fatigue. She can't stop amaze us with her social activity.

The tennis star visited the Monaco Grand Prix in Monte-Carlo on Saturday. The eight-time world champion shone in front of the cameras in a Zebra-patterned dress in the company of the Red Bull top pilots Max Verstappen and Daniel Ricciardo. Amazing show with top sports stars.

Serena Williams also posed at the high-profile event with Marvel's Thor Chris Hemsworth. The smiling tennis-player also posted a cute selfie to Snapchat with the movie star, writing, "Just hanging out with mighty Thor." Even a superstar can be a Thor's fan!
