Roger Federer posted the first photo of three-week-old twins Myla Rose and Charlene Riva on Facebook this morning.
"As promised, here is a family picture that my dad took. He thinks he's becoming a professional photographer," the tennis champ -- who also poses with wife Mirka -- writes.
Federer says the shoot was "very funny as both girls had the hiccups while we were trying to take a decent picture."
The No. 1 ranked tennis player also writes "the girls and mom are doing great" and thanks fans for their "warm wishes" on his Facebook wall.
Myla and Charlene were born July 23 in his native Switzerland.
"This is the greatest day of our lives," Federer, 27, said in a statement the day after. "Mirka, Myla and Charlene are all healthy and doing very well."
