After all the hard work and stress that comes with winning a Grand Slam, it was finally time to relax and soak it all in for Simona Halep and Rafael Nadal. As is tradition, they each celebrated with a champion's photoshoot.

A day after her securing her long sought-after first major title, Halep posed with the Coupe Suzanne Lenglen in a long black dress. 

"I kissed it many times to be sure that it's going to stay in my heart forever," she said. "It's heavy, it's beautiful. And always when I was seeing the pictures with it, I dreamed to have it, to touch it, and now it's a special moment and I'm really happy that it's mine."

The Romanian was almost familiar with the winning feeling, having won the junior title in Paris ten years ago.

She celebrated with her family and her team following the final, which she won in three sets over Sloane Stephens.

Nadal was more familiar with what to do after winning Roland Garros, having won it a staggering 11 times. He eased past Dominic Thiem in straight sets in the final, only losing one set all fortnight long. 

He had only great things to say about Halep's feat. 

"She's a great fighter. One of the players on the women's tour with better movements on court. No doubt about it," he said. She deserve it. She's No. 1 of the world. She's hard worker. I like the people who works hard that have success, because I believe that they deserve it. She's one of them. Happy for her."

Following his triumph, Nadal donned a shirt with the number 11 on it, commemorating his historic "La Undecima" feat. 

Not surprisingly, the 32-year-old looked right at home holding the Coupe de Mousquetaires trophy. Nadal and Halep are the first pair of No. 1's to win the French Open since 1992.
