Trivia: Grammy award-winning country music singer Reba McEntire was raised on a ranch in Oklahoma, where her father competed in rodeos. Immersed in Southern country culture from birth, McEntire learned to ride as well as to sing from an early age, and she formed a singing group with her brother and sister when she was young called the Singing McEntires. She enrolled at Southeastern Oklahoma State University in Durant in the mid-'70s, where she majored in teaching, but in 1975, after singing a crowd-pleasing rendition of the "Star Spangled Banner" at a local rodeo, McEntire was inspired to travel to Nashville to pursue a music career. She scored a major-label record deal and released her first album the same year she got married.It took a few years for her career to truly take off, but by the mid-'80s, McEntire was one of the most successful country singers in the industry. Though she was divorced in 1987, she remarried Narvel Blackstock, her then-manager and steel guitar player in 1989. Soon, the singer decided to branch out in her creative pursuits, appearing in the horror comedy Tremors with Kevin Bacon in 1990, the same year she gave birth to her son. Her warmth and charisma shone through onscreen, and McEntire began to cultivate a second career in acting, appearing in projects like 1994's North and 1995's Buffalo Girls. In 2001, the singer decided to switch career focuses for a while and pursue acting full-time, playing a single mom on her own sitcom, Reba. The show was a huge hit, earned her a Golden Globe nomination, and would continue to run for six seasons. She attempted to return to television in 2012 on ABC's Malibu Country, but the show was cancelled after the first season.

Trivia: Solidly built American actor Craig T. Nelson started out as a comedy writer and performer, doing radio and nightspot gigs in the Los Angeles area. Success was not immediately forthcoming, and Nelson took a four-year sabbatical from show business, moving with his family to a remote cabin in Northern California. In 1979, he made his first film, ...And Justice For All, written by his onetime partner Barry Levinson. While subsequent roles in Poltergeist and Silkwood followed, Nelson would find true stardom on television. For eight seasons beginning in 1989, he starred as college athletics instuctor Hayden Fox on the top-ranked ABC sitcom Coach. Appearing alongside supporting players Jerry Van Dyke and Shelly Fabares, Nelson received an Emmy for his work on the show in 1992.After Coach, Nelson showed up in a few small roles in feature films and television mini-series before returning to series work in 2000, leading the cast of CBS's D.C.-based cop-drama The District.

Trivia: While savvy television viewers will no doubt recognize prolific small-screen actress Wendie Malick from such popular series as Baywatch, Just Shoot Me, and HBO's smart and sexy comedy Dream On, the late '90s found her feature career warming up in such independent efforts as Manna From Heaven (2001) and Bathroom Boy (2003). A native of Buffalo, NY, who first found work in front of the cameras as a Wilhelmina model in the 1970s, the Ohio Wesleyan University alum would later work for New York congressman Jack Kemp following her graduation. Subsequently gracing the catwalks of New York, Paris, and Madrid, it was a small role in the 1978 comedy How to Pick up Girls that provided the aspiring actress with her first screen break. Though she would appear in a few theatrical releases such as Scrooged (1988) during the 1980s, most of her work came with made-for-television features and such series as Kate and Allie and Anything But Love. Increasingly visible on the small screen during the 1990s, Malick's role as series protagonist Martin Tupper's (Brian Benben) ex-wife on Dream On utilized her comic abilities to maximum effect and netted the actress four Cable ACE awards. Following the final episode of Dream On in 1996, it was only one short year before Malick began a stint on another popular series that would gain her accolades among sitcom junkies, Just Shoot Me. Her background in the modeling industry provided the ideal foundation for her role as former model Nina Van Horn, and Malick (Emmy-nominated for the role) remained with the show until its final episode in 2003, simultaneously taking occasional parts in both made-for-TV and theatrical features. In 1997 Malick took the lead in the little-seen romantic comedy Just Add Love, and following voice work as the egotistical principal in the Disney series Fillmore!, she appeared alongside Valerie Bertinelli, Jane Leeves, and Betty White the Emmy-winning comedy series Hot in Cleveland. In addition to her screen work, Wendie Malick met husband Richard Erickson while building homes for poor families in Mexico, and she also helps the homeless with her work for the Adopt-A-Family organization.
