JOHN TRAVOLTA just learned the hard way that adorable daughter ELLA BLEU, aka Daddy’s Little Princess, will turn a tad teen-moody now that she’s hit 13.

“Ella always loved hanging out endlessly with Daddy – but John got a shock when she suddenly walked away from him as he chatted with fans at the Santa Monica 3rd St. Promenade,” said a family friend.

“He spent nearly 20 minutes signing autographs and posing for pics, and Ella finally told him she’d wait in the car – then started to stalk off. John apologized to the fans, saying his little girl needed him, and Ella snapped, ‘Dad, stop calling me a little girl!’ John gushed to the fans, ‘My little girl’s really grown up, and she’s the greatest daughter!’ Ella sighed and said, ‘Daaaad! You’ve embarrassed me enough, come on, let’s go. I’m hungry!’”

The fans giggled as Ella stomped off and John hustled to catch up.

That’s when Little Princess lectured sternly: “Can’t you ever pose for just one photo? You don’t have to tell everyone your life story, Dad!”

MW NOTE: Been there, done that…with MY Little Princess!
