Zac Efron keeps his promises. After taking down 17 Again costar Leslie Mann‘s telephone number, the 21-year-old actor did indeed call her then 10-year-old daughter, Maude, on her birthday.

On Monday, Leslie dished to talk show host Ellen DeGeneres on her show: “She’s [Maude] 11 now and he called her on her tenth birthday. She was having a party and had 12 girls over and he called. It was surprise and they freaked out.”

Check out the full interview @ YouTube. The freak-out starts @ the 4:00 minute mark.
