Justin Bieber's boys' night out in NYC last night turned into something of a girls' night out thanks to 30 adoring female fans!
The 19-year-old singer hit Serafina restaurant on East 61st St. yesterday for a late supper with some pals, and it wasn't long before a crowd gathered outside the eatery. It's believed they followed his caravan of SUVs from the nearby Four Seasons hotel.
"He arrived around 11 p.m. with four friends and about five bodyguards," a fellow diner exclusively tells E! News, adding that the group of female fans "gathered on the sidewalk outside the restaurant, just waiting patiently for him."
