Bruno Mars' sisters -- Jaime, Tiara, Tahiti and Presley Hernandez -- are to star in an as-yet-untitled television docu-series in Los Angeles, WEtv announced.

The women are members of the pop band The Lylas. Their new reality show is to premiere in the fall.

"The Lylas are fierce, independent women, leaving their home -- and in some cases their relationships and kids -- for a chance at pursuing their love of music," Lauren Gellert, WEtv's senior vice president of production and development, said in a statement.

"Their story is one filled with all of the drama and chaos that comes from making a major life change, with the added spice of doing it alongside your sisters."

The show will chart the sisters' path from Hawaii to Los Angeles -- where they are living and working together on their debut album -- and their dynamic relationship as sisters-turned-business partners, the network said in a synopsis.
