Casper Ruud’s girlfriend and sister steal show at US Open after stunning pair are spotted in stands during US Open

TENNIS fans were gripped by the US Open final between Casper Ruud and Carlos Alcaraz - and not just on the court.

Ruud lost to Carlos Alcaraz in four sets at Flushing Meadows - his second Grand Slam final defeat of the year - but the show was stolen by his sister and girlfriend cheering him on from the stands.

Sister Caroline was pictured in the crowd looking stunning in a red dress.

She was joined by the world No2's partner Maria Galligani - who impressed in a black outfit.

Like Ruud, Galligani is Norwegian - and the pair have reportedly been together since 2018.

She is supposedly studying for a Master's in psychology at the University of Southern Denmark.

It is unknown what Caroline Ruud does for work but she is regularly spotted cheering on her brother at major tournaments.

She was at Roland Garros as the 23-year-old star made his ever Grand Slam final in the French Open, losing to childhood hero Rafael Nadal.

Ruud is from a tennis mad family. He has a younger sister, Charlotte, who is training to be a tennis player.

Their father, Christian, was an ex-professional player who reached a career high of world number No39. He made the Australian Open fourth round in 1997.

Ruud's rise to fame has been inspired by Nadal and he trained at the legend's academy in Mallorca when he was a youngster.

Facing him was a surreal moment for Ruud but he is beginning to get used to Grand Slam finals now.

After his first against Nadal where the Spaniard won his 14th French Open title, Ruud said: "We all know what a champion you are.

"I got to feel what it is like to play you in a final. I’m not the first victim.

“You took me into your academy. You are a true inspiration to all of us around the world."
