The girls of Fifth Harmony are killing it so far in 2015!

They are currently in the United Kingdom for a promo tour, but that aside, they have countless awesome things happening.

In recent weeks their latest single "Worth It" has broke into the Top 10 on iTunes. Speaking of their catchy track featuring rapper Kid Ink, it's now featured in a Hershey's advertisement.

On Monday, Lauren Jauregui, Camila Cabello, Ally Brooke Hernandez, Dinah Jane Hansen and Normani Kordei Hamilton dished on the 5H Twitter the news.

"Hear our song 'Worth It' in the new Hershey's Caramels commercial!" they gushed.

In the advertisement, as seen below, there is a young lady dancing around to the girls' tune while indulging on the Hershey's product. Harmonizers are thrilled that the girl group's song is featured in the commercial for the Hershey's product.

"AHHH MY TWO FAVE THING[S] CHOCOLATE AND YOU," one fan beamed.

Another Harmonizer thought the placement of "Worth It" in the ad was "SO COOL."

A different fan meanwhile pointed out how it's ironic that the girls' song is featured in a Hershey's commercial since "LAUREN HATES CHOCOLATE," which is true since the 5H singer has ranted about her dislike of chocolate before on Twitter.

Most fans though think this promo of their song is great and will help boost the single's sales.
