Zac Efron dropped condom on the red carpet at The Lorax premiere

In a video which has now gone viral, actor Zac Efron is seen approaching a fan to greet them, when he accidentally drops a condom on the red carpet at the premiere of his new Dr. Seuss film, The Lorax, at Universal Studios, Hollywood.

Zac efron, 24, swept up the contraceptive immediately, grinning sheepishly and immediately put his sunglasses on as he continued on his way.

The Disney’s High School Musical series star coughed with and held his hand to his mouth, pausing to regroup after the mishap.

The actor’s bashful smile and clear embarrassment served as apology enough- though hopefully any youngsters present might not have recognized what they saw.

Zac Efron’s co-stars Taylor Swift and Danny DeVito were also present at the screening.

There has been talk of a romance between the Zac Efron and the country singer Taylor Swift, though they have denied it.

Taylor Swift told Ellen DeGeneres during a recent appearance on her talk show: “We are not a couple. He’s awesome, we are not a couple though. You hear people get together when they’re shooting movies, co-stars.

“But not like animated co-stars. You know what I’m saying. Oh my god, as we were recording out voiceovers on separate coasts we really connected.”

Zac Efron and Taylor Swift then picked up their guitars and performed a duet as Ellen DeGeneres watched on.

They also talked about what they did for Valentine’s Day.

Taylor Swift described how she had a ‘pathetic single girls party’ where she ate lots of junk food.

And Zac Efron added: “That’s so different than what single guys do. I went to a screening of a film that I did called Liberal Arts. Then cooked some dinner with a friend.”

Rumors began to swirl about Zac Efron and Taylor Swift after they were spotted sharing a very friendly meal last month.

On January 6, Zac efron had a “flirty dinner with the country superstar” at an outdoor corner table at Los Angeles’ Pace.

Us Weekly described how Zac Efron and Taylor Swift were “were deep in conversation and very giggly”, after arriving together in Efron’s Audi.

But they have been flirting for a long time.

Back in 2009, Zac Efron – single since splitting with Vanessa Hudgens in December 2010 – called Taylor Swift a “lovely girl, very beautiful”.

In turn, Taylor Swift, dumped by Jake Gyllenhaal in December 2010, gushed that Zac Efron was an “all-around amazing guy”.
