Ashley Benson is set to visit "How I Met Your Mother" when the show returns after the winter hiatus. CBS tweeted the news, which teases that the "Pretty Little Liars" star will appear as Barney's "????" in the January 21 episode:
Since she's a little too young to be one of Barney's flames (and our suited hero is still in love with Robin), we're guessing that Benson might be playing Mr. Stinson's long-lost sister. Start speculating now!
