But after another painful Wimbledon defeat in 2015, ironically to Williams, the pair called it quits and went their separate ways - and Sharapova hasn't had a long-term relationship since.
LOVE could be in the air again for Sharapova as she has been linked with Etonian multi-millionaire Alexander Gilkes.
Nonoo, believed to be the Duchess of Sussex's favourite fashion designer, began a relationship with Gilkes in 2003 and the couple tied the knot in Venice in 2012 before separating in 2016.
Marco Cecchinato had never won a match at a Grand Slam tournament before last week but the 25-year-old Italian continued his remarkable run here on Tuesday by beating Novak Djokovic to reach the semi-finals of the French Open.
EARLY in her career, Sharapova was rumoured to have had a short relationship with the Maroon 5 singer Adam Levine after they met at her 18th birthday party.
On Friday he will meet Austria’s Dominic Thiem, who beat Alexander Zverev 6-4, 6-2, 6-1.
Combining well-timed ground strokes with stunning drop shots, Cecchinato was much the better player for most of the first two sets.
He took the first in just 34 minutes and made an early break in the second before Djokovic made a match of it after having treatment on his shoulder when trailing 5-2.
At 5-6 Cecchinato saved three set points and he won the tie-break after winning four points in a row from 3-4 down.
Djokovic, nevertheless, charged through the third set and led 5-2 in the fourth before Cecchinato fought back.
