Our gallery of Dierks Bentley pictures serves as visual proof that, this past year, the bluegrass musician has been hugely successful while having a great time. Bentley released his album 'Up on the Ridge' in June 2010, and now the album is currently No. 1 on Billboard's year-end bluegrass charts. This past year also found Bentley collaborating with bluegrass icons like Sam Bush, Ricky Skaggs and Del McCoury. To top off his amazing year in music, Bentley's personal life is also stupendous, as he and his wife Cassidy Black are expecting their second daughter right around Christmas, 2010.
