Serena & Dulko walk on water; Wozniacki & Jankovic say that's for the birds

Serena Williams and Gisela Dulko met and got wet in Monterrey, Mexico, frolicking and volleying on the water not far from the Whirlpool Monterrey Open site. Serena is not playing in the tournament due to yet another ankle ailment, but she is gamely doing press events.

See their Santa Lucia Riverwalk setup, their hitting, and their silly dancing—to Enrique Iglesias's "I Like It" and more—here:

Here's a Spanish-language TV news clip of their capering, with some nearly 12-minute fan footage here.

Meanwhile, away from the water, in Dubai, Caroline Wozniacki and Jelena Jankovic chose to play not with fire but rather ... hawks. Woz here, and JJ here.

Wozniacki's picture, in particular, looks a couple seconds away from lots of beaking and shrieking. Obviously neither has seen Alfread Hitchcock's The Birds. That was probably in their best interest.
