Hayley, David and Taylor Ann Hasselhoff star in "The Hasselhoffs"

Ballroom dancing may be all the rage, but it definitely isn't for David Hasselhoff. The Hoff was the first celeb nixed from this season's "Dancing with the Stars."

However, his time in the spotlight is far from over as he has an even tougher challenge on his plate.

The Guinness Book of World Records has named Hasselhoff the "most watched TV star in the world," but even his small-screen success may not help him with his most important role. He is, after all, a single father of two adult daughters.

Cameras capture the "stage dad" at home in A&E's new reality series "The Hasselhoffs," premiering Sunday, Dec. 5. Ten half-hour episodes chronicle the lives of the actor and his two daughters, 20-year-old Taylor Ann and 18-year-old Hayley. The girls are Hasselhoff's children with ex-wife actress Pamela Bach, from whom he split in 2006.

In the season premiere, dad David tries to convince eldest daughter Taylor Ann to stay in school, but she insists she wants to team up with her sister in the band Bella Vida. Meanwhile, Hayley lands a role on a TV series, which could mean little time for a music career. David must deal with the resulting feud.

As the series continues, the girls catch their dad in a lie after he makes a bet with them, and Taylor hires a pet psychic. It quickly becomes apparent that Hasselhoff will do whatever it takes to help his daughters achieve their dreams of breaking into the entertainment industry, whether it be as actors or recording stars.

In "The Hasselhoffs," cameras follow father and daughter Taylor Ann to the set of "The Young and the Restless," which marked a homecoming for the actor. One of his first major gigs was as Dr. William "Snapper" Foster Jr. in the daytime drama from 1975 to 1982.

He later charmed audiences as tall, dark and handsome crime-fighter Michael Knight in "Knight Rider" (1982-1986). The series followed a former detective who is given a new lease on life thanks to a self-made billionaire who needs help in his search for justice. Knight is teamed with a sentient Pontiac Trans Am known as KITT, a high-tech car equipped with artificial intelligence.

During the late '80s, Hasselhoff's focus shifted to music and he became staggeringly popular in Germany. His hit song "Looking for Freedom" (1989) was particularly big in Germany around the time of the fall of the Berlin Wall.

Subsequently, Hasselhoff made female fans swoon as strapping lifeguard Mitch Buchannon in "Baywatch" (1989-1999) and "Baywatch Hawaii" (1999-2000). It was really his role in "Baywatch" that catapulted the star to new heights as its popularity grew worldwide, making it the most watched TV show of all time, topping out at more than a billion viewers a week.

What's more, The Hoff was truly the driving force behind the series, which had initially been cancelled after a single season. It was only after Hasselhoff teamed with the creators to revive the series that it shot to the top.

More recently, he travelled the U.S. in search of unique talent as a judge on the first four seasons of "America's Got Talent" (2006-2009), but The Hoff was replaced by comedian Howie Mandel for the show's most recent run. He obviously didn't go very far in "Dancing with the Stars," but the tenacious Hasselhoff perseveres to find his place in prime time.

Despite his success, Hasselhoff often faces ridicule among critics, who refuse to take him seriously. A simple Google search turns up sites touting him as both the Antichrist and a symbol of worship (though admittedly in a tongue-in-cheek manner).

While there are no shortage of quips about him, The Hoff is quick to poke fun at himself, often doing so in cameos in popular movies. Hasselhoff appeared as a "Baywatch"-esque version of himself in "The SpongeBob SquarePants Movie," and followed that up with self-parodies in "Dodgeball: A True Underdog Story" (2004), "Click" (2006) and "Kickin' it Old Skool" (2007).

He showed he was a good sport during a Comedy Central Roast, which aired this summer. Former "Knight Rider" co-star William Daniels (who voiced KITT), joined such celebrities as Pamela Anderson and Hulk Hogan to take jabs at The Hoff.

It's proved to be a good thing he has a sense of humor about himself. He's already been the victim of a reality check that might have otherwise destroyed a thinner-skinned celeb. In 2007, daughter Taylor Ann filmed a drunken Hasselhoff trying to eat a cheeseburger in a Las Vegas hotel room. The video caused quite a stir when it spread wildly across the Internet, even leading to a temporary suspension of his visitation rights with his two daughters.

Since then, rumors of drinking binges and hospitalization due to alcohol poisoning have surfaced, but Hasselhoff's representatives have denied such claims.

Those expecting to see such antics in A&E's "The Hasselhoffs" will likely be disappointed. The focus appears to be squarely on the trials and tribulations of single-dad Hasselhoff and his daughters' struggle to break into the entertainment biz.
