Vitalii Sediuk strikes again. 
 
 The 25-year-old Ukrainian journalist somehow made his way onto the red carpet at the 20th Annual Screen Actors Guild Awards in L.A. on Saturday, Jan. 18. Once there, he wrapped his arms around an unsuspecting Bradley Cooper and nestled his face in the Silver Linings Playbook star's crotch. 
 
 Cooper, 39, initially appeared to laugh off the gag as his American Hustle costar Michael Peña and actor Mandy Patinkin look on in disbelief. They then helped Cooper pry Sediuk from the actor's legs. 
 
 Given his past antics, Sediuk's SAG Awards stunt was relatively tame. 

 Police arrested a serial prankster after he confronted Brad Pitt on the red carpet at the Hollywood premiere of the movie “Maleficent.�? 
 
 Witnesses saw the man -- identified as Vitalii Sediuk, 25, a notorious red carpet prankster -- jump over a barrier to the red carpet at the El Capitan Theatre in Hollywood Wednesday. The man approached Pitt and came into physical contact with him, Los Angeles police said.

 Sediuk is well-known for his stunts. He recently tried to climb under America Ferrera's dress on the red carpet at the Cannes Film Festival. He also crashed Adele's Grammy win in 2013, storming the stage after she was announced the winner of best pop solo performance. He also famously tried to kiss Will Smith a year earlier.

 "Maleficent" carries deep connections for Pitt, with Jolie starring and daughter Vivienne Jolie-Pitt, 5, in her first movie role as young Princess Aurora. Vivienne’s siblings Zahara and Pax also have walk-on roles in the film. 
 
 The film was developed by Disney, the parent company of ABC News.

 A man was arrested Wednesday night after physically attacking Brad Pitt at the world premiere of “Maleficent,” starring Pitt’s partner Angelina Jolie. 
 
 Witnesses saw the individual, later identified as celeb prankster Vitalii Sediuk, jump the security barriers while Pitt and Jolie were signing autographs in front of the El Capitan Theatre in Hollywood.

 Security guards held Sediuk, 25, until the LAPD could take him into custody, which you can see in the paparazzi video below. LAPD Sgt. Leonard Calderon said he was taken to the Hollywood police station where Sediuk was arrested and booked on suspicion of misdemeanor battery. 
 
 He is being held on $20,000 bail. 
 
 Pitt, who was unharmed according to law enforcement officials, resumed signing autographs for fans after the incident. 
 
 “This was an unfortunate and inappropriate incident that is being investigated by the LAPD,” a spokesperson for Disney, the distributor of “Maleficent,” told Variety.

 Ukranian TV presenter Sediuk was last spotted just 11 days ago in Cannes with his head under America Ferrera’s dress. The notorious prankster crashed the Grammys last year, when he was jailed overnight and banned from setting foot in the L.A. Live complex after making it up on stage and attempting to accept Adele’s award for best solo performance. He has also grabbed Leonardo DiCaprio (watch the video below), tried to kiss Will Smith (and was subsequently slapped) and groped Bradley Cooper at various red carpet events.
– Brad Pitt and Angelina Jolie appeared unfazed last night after a man jumped over a barrier and allegedly hit Pitt in the face at the Hollywood premiere of Maleficent; police said the man "came into physical contact" with the actor, per ABC News. Guards hauled the man—later identified as Ukrainian "prankster" Vitalii Sediuk, 25—off the red carpet and he was arrested and charged with battery. Pitt was unharmed and resumed signing autographs after the incident. Sediuk's bail was set at $20,000. "This was an unfortunate and inappropriate incident that is being investigated by the LAPD," a spokesperson for Maleficent distributor Disney tells Variety. Sediuk's previous run-ins with celebrities have included kissing Will Smith, planting his face in Bradley Cooper's crotch, and—most recently and creepily—diving under America Ferrara's skirt in Cannes earlier this month.
