Love is in the air for two of Hollywood's stars.

While they surprised everyone with this very unpredictable pairing, "2 Broke Girls" actress Kat Dennings and Grammy nominee Josh Groban have publicized their relationship.

"Kat and Josh recently started dating and are having a lot of fun," a source told Us Weekly.

Dennings also posted a red carpet photo of them on her Instagram account and wrote, "I ship it."

Rumors about the two started when they attended the 2014 Carousel of Hope Ball in Beverly Hills together on Saturday, October 11. The two posed for the red carpet cameras as they both had their arms around each other. Dennings was also photographed whispering something in Groban's ear and laughing with him.

Both looked stunning wearing black, with Dennings wearing a low-cut gown that hugged her curves, and Groban looking appropriately handsome yet scruffy in his tailored suit.

Their photos certainly capture their attraction towards each other, as the happiness in their pictures is undeniable. The two were definitely not just friends as they were practically joined at the hip in every photograph they had at the Carousel of Hope Ball.

Dennings was reportedly present for the diabetes event to only support Groban, who performed three songs.

Before they dated each other, Groban went out with "Mad Men" actress January Jones for three years before they split up in 2006. He also said that he and Katy Perry had a short fling.

Dennings, on the other hand, was linked to "2 Broke Girls" co-star Nick Zano.
