Bradley Cooper was left red-faced when a prankster tried to hug from the waist down.

The 'American Hustle' star became the latest victim of Ukranian TV reporter Vitalii Sediuk - who previously attempted to interrupt Adele's speech at the 2013 Grammy Awards - at the Screen Actors Guild (SAG) Awards in Los Angeles on Saturday (18.01.14) when the practical joker got a little too close to Bradley's nether-regions.

As the 39-year-old hunk walked the red carpet, Vitalii seized the moment by wrapping his arms around the actor's waist and planted his face firmly in his genital area.

An embarrassed Bradley tried fervently to free himself from the known jokester's clutches as fellow Hollywood stars Mandy Patinkin and Michael Pena helped him. Eventually, Vitalii relented and rose to his feet on his own accord.

It's not the first time the 25-year-old Ukrainian has hit the headlines for his celebrity antics.

In 2012, he was slapped in the face by A-list actor Will Smith after planting a kiss on his cheek at the Moscow premiere of 'Men in Black III'.

And just last year, the TV prankster raised security questions when he managed to sneak into the Grammy Awards without a ticket and took Maroon 5 singer Adam Levine's unused seat.

Vitalii later made his way to the stage and attempted to interrupt singer Adele as she collected the award for Best Pop Solo Performance from presenter Jennifer Lopez.

The intruder tried to claim the award as his own but was quickly ushered away by Jennifer.
