Kaley Cuoco is the new face of skincare brand Proactiv.

'The Big Bang Theory' star's representative confirmed that she is the newest face of the range although the start date for her campaign has yet to be announced.

The 26-year-old actress follows in the footsteps of the pimple treatment line's star-studded roster, which includes Avril Lavigne, Justin Bieber, Naya Rivera and Katy Perry.

'Glee' star Naya, who is a longtime fan of the famous three-step acne-clearing system, signed on as the brand's celebrity spokesperson in December 2011.

The 25-year-old said at the time: ''The makeup artist on the set of Glee gave it to me and I kept it using it because I knew it worked for other people. I really wanted to work with Proactiv because the products really helped me.''

Kaley - who is filming season six of her sitcom - took to twitter to reveal she is ''so thrilled'' about her latest gig.

She has recently tweeted her love for another skin product, Josie Maran's Argan Oil Moisturizing Stick.

She wrote: ''The Josie Maran beauty balm stick is my new favorite thing ever! Thanks @jamiemakeup for letting me steal it from you :)''
