Emily Osment keeps true to the sponsor as she snaps a few pics at Z100 & Coca Cola’s All Access Lounge pre-show at Hammerstein Ballroom in NYC on Friday afternoon (December 10).

The 19-year-old singer is reuniting with her former on-screen beau Mitchel Musso for a holiday concert NEXT WEEK!

Thanks to our friends at Fanlala for the news, the former Hannah Montana couple will join Ashlyne Huff, One Call, Savvy, and a few others for the 2010 Salvation Army Rock The Red Kettle Concert.

The concert will also be streamed live via Ustream where supporters can click to donate while watching the show. Donors can also make a $10 donation to the campaign by texting the word “GIVE” to 85944.

Money raised during the campaign helps the Army serve nearly 30 million Americans in need each year in communities nationwide through a wide array of programs including toys for kids, coats for the homeless and food for the hungry.

This is a FREE concert and open to the general public. It all starts @ 7PM ET at The Americana at Brand in Glendale, Calif., on Wednesday, December 15th.
