Blake Lively might be at the top of her game now – but when the “Gossip Girl” star was 3 years old, her teacher thought she was struggling with a learning disability – but only because her mom lied about her age.

“When I was only 3 years old, my mom enrolled me in the first grade. My older brother was supposed to start school, but he didn’t want to go alone, so my mom told them I was 6 since I was so tall,” Blake said in an interview with Marie Claire in it’s December issue. “But after a few weeks, they said they would have to put me in mentally disabled classes because I wasn’t up to pace with the rest of the kids.”

The actress said her toddler instinct to for naptime wasn’t welcomed in her first grade class.

“They thought that I was slow because all I wanted to do was sleep while the other kids were doing their projects,” she said with a laugh. “So my mom took me out of school.”

Blake’s mom might have caused concern when she lied about her daughter’s age, but she made up for it with frequent childhood trips to Disneyland.

“I kind of feel like I grew up at Disneyland,” Blake explained. “My mom would take me there twice a week. I did well in school, so I guess my mom just wanted to have some extra time to bond with me. Sometimes, when I was older, she’d keep me out till one in the morning. We only stayed out late on weekends. We’d get a hotel room and then go to Denny’s, drink coffee, and talk for hours.”

Blake says her late night adventures with her mom have helped her to become a better actress.

“I’ve always been a night owl. Even at home, we’d stay up all night talking. My mom tells the most amazing stories,” she told the mag. “In a way, she was kind of raising me to be a great actress without even realizing it.”

Blake Lively has no ”willpower” when it comes to dieting, and because of her eating habits hates having to flash her flesh on screen.

Blake Lively is petrified of baring her flesh on screen.

The ‘Gossip Girl’ actress – who plays Serena van der Woodsen in the hit US TV show – hates having to wear tiny clothes for the programme because she doesn’t bother watching what she eats.

She explained to Britain’s Glamour magazine: “I do panic before I have to wear a really skimpy outfit, but I don’t have enough willpower. I had to do a scene in a bra and shorts for the first time in two years.

“On the day of the shoot, I had a pork burrito, chips and coke. Afterwards, I thought, ‘I probably shouldn’t have done that.’ But whatever.

“I have never worked out, but I know you feel better when you do so I am planning on getting a trainer.”

Blake is currently dating her co-star on the show Penn Badgley, but admits their love story was not as smooth as people think.

The 21-year-old actress was initially totally opposed to Penn getting a part on the show, but her opinion of him changed when they began working together.

She said: “At first I was so upset that they hired him. I actually poisoned the whole cast against him. But then they noticed that he wasn’t a jerk and was actually a really nice, charming person. Almost immediately I realised that too, but it took me about a week to admit it.”
