From US Weekly:
“Kat and Josh recently started dating and are having a lot of fun,” a source tells Us Weekly.
The pair first sparked rumors on Saturday, Oct. 11, when they attended the 2014 Carousel of Hope Ball, an event sponsored by Patron Tequila, in Beverly Hills together. Posing with their arms around one another on the red carpet, Dennings was photographed whispering in Groban’s ear and laughing with her new beau.
How strange! I guess odd couples tend to work out well sometimes, so we’ll see how this one goes. I never, EVER would have even put these two in the same room, let alone in a relationship. Huh, go figure!
