Serena Williams is missing out on one of her favorite tournaments in Rome this week. While she's got to be feeling a little left out, it has given the 35-year-old expectant mother reason to share an epic "warm up" clip from a past trip to the WTA Premier event. 

While Williams isn't in Rome, her family members are. Her mother Oracene has been spotted supporting Venus Williams. 

While the 36-year-old is still focused full-time on the tour, she's got one eye on her future as an aunt. 

The elder Williams sister is seeking her first Rome crown since winning it back in 1999.
