World No.1 Iga Swiatek immediately noticed her post-match blunder in a hilarious moment after her quarter-final win against American Jessica Pegula.
Swiatek bounced back to form in a 6-3, 6-2 victory over Pegula to extend her unbeaten run on the WTA Tour to 33 victories.
'UNSPORTSMANLIKE': Russian star embroiled in French Open furore
The recently turned 21-year-old has thrived since taking the World No.1 ranking and will face Daria Kasatkinda in the semi-final.
However, Swiatek made a hilarious blunder during her post-match celebrations at the French Open.
As she was leaving court, Swiatek wrote a message on the camera as is customary for players these days.
However, Swiatek momentarily got ahead of herself and wrote '22' on the camera.
She instantly said: "Oh no" when she realised the mistake, having only turned 21 on Wednesday.
"I forgot how old I am," she quickly said.
Social media was quick to share a laugh with the Polish World No.1 over her mistake.
Iga Swiatek wrote 22 on the lens & said she forgot how old she turned yesterday!
Maybe it's not the age, but the year of her next French Open title 😉 https://t.co/TYY4Far4IO

She has better things to do than remembering her age 🙈

While Swiatek may only be 21 years old, she heads into the semi-final as the only woman to have reached this stage of the remaining contenders.
Iga Swiatek heavy favourite in French Open final four
Swiatek has previously participated in the semi-finals of a major tournament, losing at that stage at the Australian Open in January and taking the title at the 2020 French Open when she was ranked outside the top 50.
"This year it's a little bit different, because I'm not an underdog," Swiatek said, "and everything has changed, honestly."
Her opponent, Kasatkina, beat World No. 29 Veronika Kudermetova 6-4, 7-6 (7-5) in a match between two Russian players who will not be allowed to compete at Wimbledon later this month because of that country's invasion of Ukraine.
They combined for 75 unforced errors, 50 by Kudermetova.
Following the match, Pegula paid respect to Swiatek and compared her game to retired Aussie Ash Barty in a huge compliment.
"To be honest, she (Swiatek) kind of plays like a guy. And, I mean that as, Ash (Barty) was a similar way, where they don't play like a typical girl where they hit kind of flat and the ball kind of goes through the court," Pegula said.
"She plays a little more unorthodox in the fact that she has, like, a really heavy forehand. But at the same time she also likes to step in and take it really early, and I think clay gives her more time, and I think it makes her forehand even harder to deal with."
