"The Voice" is about to sound even sweeter now that Reba McEntire, Monica and other music favorites are joining the NBC singing competition.

In the coming weeks, coaches Blake Shelton, Christina Aguilera, Cee Lo Green and Adam Levine will be teamed up with mentors from the music industry who have inspired them, according to the network.

McEntire will join Shelton, Monica will join Cee Lo Green, singer Sia will join Aguilera, and Maroon 5 music director Adam Blackstone will join Levine.

The quartet will serve as advisers to their colleagues as well as the talent, offering words of wisdom and helping to choose songs that best suit each singer's vocal style. -[CNN]

Cee-Lo is already huge (no pun intended), and it looks like Christina Aguilera collaborator Sia is on her way towards major stardom as well.

And in addition to Sia's upcoming spot on TV, she'll appear live across North America on tour in July and August with special guest Oh Land opening the shows. The tour includes two NYC nights at Webster Hall, July 26 & July 27. Tickets for the 7/26 show go on AmEx presale on Wednesday, and general sale at noon on Friday (5/6). Tickets for the 7/27 show will probably go on sale when that one sells out? Tickets for the 7/27 show also go on presale/sale Wednesday/Friday.

Oh Land recently performed at Terminal 5 with the return of OMD, at The Charles Bank Gallery and at Best Buy Union Square. Video of Oh Land from T5 and Best Buy, and all tour dates, below...
