Jennette McCurdy Covers Katy Perry’s ‘Unconditionally’ [VIDEO]

Jennette McCurdy might have a little time off from her starring role on 'Sam & Cat,' but that doesn't mean she's not appearing in front of a camera.

The 21-year-old actress and singer is making the most of her holiday break, by sharing her amazing voice in a new YouTube video that finds her performing Katy Perry's 'Unconditionally.'

In the clip posted Dec. 24, she covers the hit without accompaniment, singing directly into the camera from only inches away. She manages to produce a powerful sound, even though she's lying on her stomach for the entirety of the performance. Jenn appears to be on her bed -- which is unmade, BTW. (Hey, it's the holidays!)

The former 'iCarly' star currently appears on Nickelodeon's 'Sam & Cat' with bestie Ariana Grande, who knows a thing or two about singing herself. Jennette released a country-music album in 2012, but parted ways with her label later that year.

She has continued to develop her musical interests, however, posting a variety of songs on her YouTube channel, including her cover of 'Take It All' by Adele.

Perry has said that 'Unconditionally' is her favorite song on 'Prism,' calling it "the crown jewel of the record." Check out Jennette's version above!
