Roger Federer and wife Mirka are the proud parents of twin girls, Charlene Riva and Myla Rose.
The birth of the twins means that Wimbledon 2029 and onwards will see a new horizon of William Sisters-like dominance by the feared Federer twins.
The FFT (Feared Federer Twins) will dominate tennis early, and will face stiff competition only later on in their careers by the hungry Nadal triplets, and the Roddick quintuplets.
Look for Charlene and Myla to switch number one and number two spots like they have a secret deal between them. They will hold press conferences at lightening speed because they will be able to finish off each other's sentences in four languages.
This news does not bode well for the rest of future groups in Ladies' tennis because everyone knows what one Federer can do on the men's side.
Will Roger approach the Williams sisters for coaching techniques or will he teach his daughters all the tricks in lobs, drop shots, forehand, and backhand shots?
The bigger question is will mother Mirka be patient enough to watch more tennis matches involving her daughters as she has with her husband.
Rumour has it that Nike has already designed some infant gear including tiny shoes, shirts, skirts, and mini-tennis rackets.
It won't be long before infant tennis rallies take place between the two cribs in the baby room.
Congratulation to Roger, Mirka and their respective families on this most jubilant day!
