Run Eva, run! Just a few weeks after announcing her plans to divorce NBA star Tony Parker, Eva Longoria is already being chased by singer and lothario John Mayer.

"John is crazy about Eva," a friend of Mayer's told PopEater. "There is something about newly-divorced ladies that drives him nuts. He was the same way over Jessica [Simpson] when she left Nick [Lachey], and now he has his eye on Eva."

But Mayer, who in recent months has been linked to Taylor Swift and celebrity chef Giada De Laurentiis, won't be sweet-talking Longoria on a date anytime soon. "No way is Eva thinking of another man right now," a friend of the Desperate Housewives star said. "Mayer can send all the flowers in the world and even show up under her window with his guitar and it would make no difference. Eva wants some alone time. She is still heartbroken about her marriage falling apart."

Longoria filed for divorce in mid-November, ending her marriage to Parker after three years amid rumors of infidelity on his part. –ISHITA SINGH
