Roger Federer and his wife posted the very first photo of their 3-week old twin daughters on Facebook this weekend.

“Here is a picture my dad took. He thinks he’s becoming a professional photographer,” Federer said regarding the picture shown above. “It was funny … both girls had the hiccups as we were trying to take a decent picture. The girls and mom are doing great. Thanks for all your warm wishes.”

The twins, Myla Rose and Charlene Riva were born on July 23rd in Switzerland. Also shown in the picture is his wife Mirka, who he married in April.

We can’t tell much from the one photo he posted, but they look more like daddy than mommy.
