During a concert in Dublin, Ireland on Feb. 17, Justin Bieber flaunted his abs to the audience when he removed his shirt.

The singer kicked off the European leg of his Believe tour with a performance at the O2 Arena in an all-white ensemble. Before he revealed his abs he tweeted "Ireland the #BELIEVEtour is back and in EUROPE! Leggo!" followed later by "I'm in the building dublin." 

The 19-year-old has showed off his abs numerous times before, most recently during Saturday Night Live on Feb. 9.

During one of the show's skits, Bieber played himself and was introduced to 12 body doubles consisted of the entire SNL cast, male and female. Jason Sudeikis was his head of security, introducing the singer to his body doubles brought in as an added security measure to protect him from his fans. The doubles attempted to prove that they could mimic Bieber's famous wink, his dance moves and his "swaggy" way of talking. However, when Bieber raised his shirt and showed off his abs, none of the doubles could copy that and one even walked off the set.

Bieber hosted SNL on Feb. 9 for the first time and also performed two songs that night: an acoustic version of As Long As You Love Me and Nothing Like Us, which he admitted was inspired by his breakup with Selena Gomez.  

Only a few days after he showed his abs to a Ireland audience, Bieber was spotted with two girls after a "boys nights out" in London, according to Hollywood Life. He reportedly went to a few clubs with Will.i.am. and members of The Wanted, and was then photographed returning to his London hotel around 4 a.m. with two unidentified girl - one blonde and one brunette. The unidentified brunette wore a fun black top with leopard-print pants, while the unidentified blonde was wrapped in fur.
