With his "The Singing Bee" hosting work, upcoming "Mad TV" and "Hannah Montana" guest stints, and sundry promotional and other activities, nice-guy entertainer Joey Fatone barely knows whether he's coming or going of late.
"I'm just taking it a day at a time. We've been in a crunch, but now we're reaching the point we're able to take a little more time," says

Fatone, whose popular Tuesday-night NBC "Bee" was rushed onto the air last summer to get a jump on Fox's similar "Don't Forget the Lyrics!" "It's nice getting into a rhythm, seeing what works."

The one-time 'N Sync baritone tells us that coming up, there'll be a TV theme song edition -- with appearances by familiar faces such as Alfonso Ribeiro of "The Fresh Prince of Bel Air."

Fatone also treks Down Under to host the Australian version of the show. "It's really cool to see the different cultures. Of course, they had some Australian songs that I had no clue what they were." How do the Aussie contestants stack up? "They're funnier. They really make stuff up if they don't know the lyrics."

Joey, who's looking forward to a holiday break with wife Kelly and their 6-year-old daughter, Briahna, says, "I'm not really the solo artist type, but something may be in the works" as far as his own singing career. "We're talking about a fun possibility."

Meanwhile, he has a list of events he'll be covering as red-carpet preshow host for the TV Guide Network next year. He also wants to do more acting. Having done Broadway ("Little Shop of Horrors," "Rent") and film ("My Big Fat Greek Wedding," "The Cooler") and come in second on "Dancing With the Stars," he knows of what he speaks when he says, "I love all aspects of entertainment. I love doing it all -- and I want to do well enough where I don't suck." So far, that hasn't happened.
