Lachey, former frontman of the boy band 98 Degrees, will host the show that sees eight acappella groups competing for a $100,000 prize and a contract with Sony Music Entertainment’s Epic Records with America’s votes.

Nick and Drew Lachey stop by Are You Smarter Than A 5th Grader? Tues., Nov. 10 @ 8 and 8:30PM ET/PT on MyNetworkTV.

According to The National Enquirer’s “Gossip With Mike Walker” Column, Jessica was stunned speechless when the former 98 Degrees singer shot down her suggestion that they meet up for a drink before she left the country to begin filming her VH1 reality series, The Price of Beauty earlier this month.

Lachey parted ways with longtime girlfriend Vanessa Minnillo in June, while Simpson split from Dallas Cowboys star Tony Romo on the eve of her 29th birthday.

Enquirer spies describe the conversation between the phone conversation between the two as “awkward.”

“After about 15 minutes of pleasantries, Jessica finally got up the nerve to ask if they could get together for a drink,” a tattling tipster reveals.

“He was very to the point,” says the spy, “Jessica wasn’t prepared for it. He said he was sorry about her breakup with Tony, but getting together for a drink, dinner, or anything at all was not in the cards for him — now or ever.”

Jessica was crushed as Nick added, “It’s best to leave things as they are.”

Former boy bander Nick Lachey and teen beauty queen turned MTV VJ Vanessa Minnillo have broken up after three years of dating.

“They have amicably split but remain good friends who still greatly care for one another,” a publicist for Vanessa, 28, tells PEOPLE.

Nick, 35, began dating Vanessa shortly of his divorce from singer Jessica Simpson in June 2006.

Nick Lachey is still planning to release his third studio album, titled Coming Up For Air, later this year.

The former star of MTV’s Newlyweds released single the LP’s lead single, “Patience,” to limited fanfare earlier this year. Nonetheless, Nick is giving it the old college try one more time with the debut of his new single, “All In My Head.”

PLAY “All In My Head” By Nick Lachey

Rock It or Drop It?

Nick will play himself on an episode that features the former MTV reality-star visiting Tree Hill after “Haley” is hesitiant to sell a song she wrote for Nick to a record label.

The former 98 Degrees singer says he is shocked by the vast media coverage of the story.

“I can’t believe it’s this big of a story and people are making such a huge deal about it. I’m never ceased to be amazed by people’s reactions to things,” Nick said in an interview with Extra on Friday.

“I wish her nothing but the best and I hope she’s happy — whatever size that comes in.”

Nick, 35, and Jessica, 28, were married from 2002 to 2006. Nick is currently dating former MTV VJ Vanessa Minnillo.

Faced with the likelihood that her career country music could be a short-lived one, Jessica Simpson is working on Plan B. The “Come On Over” singer has approached ex-husband Nick Lachey about once again joining forces on a new television show.

The former lovers have each experienced a career drought in the years since their hit MTV reality series Newlyweds went off the air.

“It’d be like Sonny and Cher, who continued their TV show after their divorce – and a field day for joke writers,” a spy revealed to the National Enquirer on Wednesday.

Don’t expect any ego-trippng from beau Tony Romo if Nick agrees to once again join Jess on the small screen; “Tony doesn’t see Nick as a threat, and he’d love Jess to stay busy during football season.”

On Monday, Britain’s Daily Sport claimed a sex tape featuring the singer/actress in a raunchy romp with then-husband Nick Lachey had been left by the people responsible for leaking the Pamela Anderson/Tommy Lee sex tape

There is “no truth” to the story, Simpson’s spokeswoman Lauren Auslander emphatically told TheCelebrityTruth.com Thursday. The publicist added that no Jessica/Nick sex tape exists.

The footage has reportedly fallen into the hands of the same individuals responsible for leaking the Pamela Anderson and Tommy Lee sex video, and the thiefs are threatening to leak the tape if Jessica does not pony up an undisclosed amount of dough.

“Jessica is horrified her name and sex tape are being mentioned in the same sentence. She’s always been a girl of high morals and principles,” a source told the Daily Sport of the alleged X-rated flick.
