It was a full house on day one at the French Open yesterday, which kind of makes you see the advantages of it starting on a Sunday, unlike the regular Monday start at the three other Slams.

Venus Williams enjoyed a solid opening round victory and later revealed she hadn’t yet read her father’s recently released book, “Black and White: The Way I See It”.

The 33-year-old American has a good reason though.

She’s going to school.

Business school that is, as she hopes to get a better handle of her fashion line, EleVen by Venus.

“I’m in business school. I have like four classes, so I don’t really do a lot of leisure stuff. I just do a lot of reading and stuff,” said the eldest Williams sister.

“I’m at Indiana University East. I’m officially a Red Wolf.”

The American, who turns 34 in a couple of weeks, is in constant struggle with the energy-sapping Sjögren’s syndrome but is back in the top 30, thanks to winning in Dubai earlie this year.

Meanwhile, her sister Serena warmed up for her title defence by attending some of the Kanye West-Kim Kardashian wedding festivities in Versailles.

As you’d normally do ahead of a Grand Slam of course.

She was also asked about the supportive tweet she sent Caroline Wozniacki following the Dane’s break-up with golf star Rory McIlroy.

What’s easier for Serena, a loss on court or a break-up?

“I would rather lose any day than break up. It’s always hard,” said the world No1. “Definitely easier to take a loss because you always have next week.”

Besties: Serena had dinner with Wozniacki on Sunday night in Paris.
