Sen. Scott Brown knows how to celebrate.
Shortly after being sworn into the Senate Thursday, the currently one-time Cosmopolitan magazine centerfold stopped by the Dubliner for a little celebrating.
An ITK spy spotted the Republican senator from Massachusetts sitting near the window of the popular Capitol Hill watering hole at 6:45 p.m., less than an hour after Vice President Joe Biden finished administering the oath of office, The Hill reported.
Brown was drinking Guinness and being serenaded by Irish tenor John McDermott, according to our spy.
And, according to the Hill, that may not have been the new senator's last stop of the night. Brown's supporters were allegedly planning on stopping the Union Pub to top the night off.
