Azalea shares her excitement for the new gig in a statement which reads: "I am so excited to bring back this iconic show for another generation of teenagers.
"The biggest impact that House of Style had on pop culture is its ability to make fashion fun and interesting to fans who are both diehard fashionistas or not at all."
Over the eight-episode season, Azalea will seek out the latest street style trends and tour music video sets with the likes of Rita Ora and designer Jeremy Scott.
The new House of Style series will premiere in the U.S. on 4 August (14).
