Steven Tyler - Lopez Stunned To Find Steven Tyler Swimming Naked In Vegas

The talent show personalities headed to the Wynn Las Vegas resort last week (begs16Jan12) to film an upcoming episode of Idol and they took time out of the shoot to catch a performance of the venue's in-house show Le Reve - The Dream, which features artists dancing underwater.

The show prompted Tyler to later shed his clothes and go skinnydipping in the hotel pool - but his nude swim caught Lopez by surprise.

During a joint appearance on America's The Tonight Show with Jay Leno on Friday (20Jan12), Idol host Seacrest explained, "We flew back from Vegas last night, we were shooting an episode there of Idol... and at the end of a final performance from a contestant, I heard this scream from Jennifer Lopez and I looked up and she was standing over the Le Reve pool. It's a water show, so she's standing over the edge and screaming, looking down at a naked body in the water!"

The nude culprit was identified on the talk show as Tyler and he laughed off the incident with a quip about trying to bed Lopez with his saucy stunt.

Tyler joked, "Hey, I'm from Boston! I love water... Well I sat at La Reve all week and I just thought, I've watched the show all week and I'm a water guy and... I just wanted a good excuse to take my clothes off in front of J.Lo."

Asked what he expected Lopez to do, he burst into song, singing the chorus of Frank Sinatra's High Hopes: "'Cause we had, high hopes...!"

But Tyler insisted he wasn't embarrassed by the incident - because he loves teasing Lopez.

He added, "I live to try to make her blush, I live for it, oh yeah!"
