Serena & Venus Williams' 75 y.o father files for divorce from his wife

Richard Williams, tennis champs Serena and Venus Williams' 75-year-old father, has filed for divorce from his much younger wife in West Palm Beach, Florida.

In his petition, the 75-year-old tennis coach often credited for training his daughters in their younger years and laying the foundations that eventually made them into tennis superstars, believes his 38-year-old wife of seven years, Lakeisha Williams, is an alcoholic.

He also claims she is stealing his social security checks and transferred ownership of their cars and a house to herself by forging his signature.

Williams, who married Lakeisha in 2010, also claims she moved out last year and left their now 5-year-old son, Dylan, in his exclusive care. Lakeisha is barely older than his two two daughters - Serena is 35 and Venus will turn 37 on Saturday.
