Vanessa Hudgens was busted during an interview with Jay Leno on the Tonight Show, after the talk show host asked her about a tattoo that was spotted on her foot during a Hudgens’ recent vacation in Hawaii.

Hudgens, 23, was photographed romping on the beach in a bikini, and although she has a few tattoos, this one was new.

A close up photo of her foot showed writing that appeared to be inked on. The tattoo said “All You Need Is Love.” The line is from a well-known Beatles song.

Tattoos are all the rage, of course, among celebrities and musicians. Young stars are part of the trend. Aside from Hudgens, celebrities like Justin Bieber and Miley Cyrus have been steadily adding tattoos.

So, Jay was naturally curious to her the story behind her latest body ink. After they made small talk with guest Daniel Radcliffe, Jay held up a tabloid showing a photo Hudgens in a bikini. And, an inset photo showed the tattoo.

“Now go down to the foot. What is that? You got a tattoo,” said Jay. “What does it say?”

Oh…” Vanessa sighed. “It says All You Need is Love… which is true.”

If Jay knew it was fake, he sure played it like he didn’t. “Is that painful though, a tattoo on your foot?” he asked.

Hudgens could have gone with it, but instead, she giggle and said sheepishly, It’s faaake.”

Oh… It’s fake?” Jay replied in surprise.

“I have this mad obsession with drawing on myself, like, I cannot help it. I draw all over my hands, all over my arms, obviously my foot. It’s just fun. It’s hard to commit to a tattoo, like, I have a few, so, when you write on yourself it’s not that much of a commitment,” she explained.

“I did that in school, but it was mostly the answers,” said Jay, warming up to his hilarious discovery.

“So you’re not sure all you need is love. You want to see and wait awhile,” he continued.
