Spanx footless pantyhose founder Sara Blakely probably isn't footing those new baggage fees at the airport these days.

The Atlanta entrepreneur is sporting a new engagement ring from Marquis Jet co-founder Jesse Itzler, 39, who recently was selected as one of the "Forty Under 40" by biz bible Crain's New York.

"Their lives have really been on a parallel track," Blakely rep Misty Elliott tells Buzz. "They're such an amazing match. We couldn't be happier for them."

At the dawn of the millennium, around the time Blakely's revolutionary slimming pantyhose brand was shaping up, Itzler's company, which "rents" jets to folks in prepaid 25-hour increments, was taking off.

According to Crain's, Itzler's company boasted revenues of more than $700 million in 2007.

The pair first got acquainted when Blakely became a Marquis client. When she launched her Sara Blakely Foundation in Atlanta in 2006, Itzler was among the first donors to write her a check.

Blakely, 37, , has built Spanx into a multimillion-dollar retail operation touted by Oscar-winning actresses and Oprah Winfrey.

We hear that an October island wedding is being planned in either the groom's native New York or the bride's birth state, Florida.

Early last year, Blakely and Åtlanta businessman Lawton Ursrey amicably ended a brief engagement.

Oh, and if Blakely and Itzler should want to economize on the entertainment budget at their wedding reception this fall, Itzler could always pick up the microphone.

In the early 1990s under the moniker Jesse Jaymes, Itzler's white boy rapper persona scored the MTV favorites "Shake It (Like a White Girl)" and "College Girls."

Lots of daughters heard Keys concert

The ticket may have said it was the Alicia Keys' "As I Am" Tour, but it sure looked like Daughters Night Out. Everywhere you turned Wednesday night, there were moms and daughters, dads with daughters, families with daughters, all at Philips Arena to see one of the most talented and inspiring female artists in contemporary R&B music.

Let's hope mom or dad covered their ears when "American Idol" Jordin Sparks got a little sad before Keys sang "Freeze," and told the audience to cherish each other "because you guys, we don't know how long we're going to be here."

Here's hoping the little ones' eyes were shielded as well when one of Atlanta R&B singer-songwriter Ne-Yo's dancers pranced in front of him, in lingerie, during "Mirror" and "Say It."

And with all of that early use of their hands, maybe they didn't mind only having sporadic things to applaud during the main attraction, like Cedric the Entertainer's sermon in the opening video and Keys' dynamic performance of Prince's "How Come You Don't Call Me" in the middle of the sometimes sleepy two-hour set. Whenever her piano was rolled out, Keys stopped with the choreography.

Of course Buzz couldn't let Ne-Yo go without asking him to discuss his one-time tour mate —- R. Kelly. "Thankfully, there has been no R. Kelly craziness on this tour," he said. "And at first I was getting kind of worried because the first two shows with Alicia didn't happen because she got sick. And I only did two shows with R. Kelly, and I was gone. So I was like, 'What is it with me touring and two shows?' But the Alicia thing got going and it's been good. Great."

And what about Kelly finally going to trial on child pornography charges: "All I can say about that is, 'Pray for that man.' "

'Modern Marvels' goes all medieval

The History Channel's "Modern Marvels" travels back to the Middle Ages this week with help from Medieval Times Dinner & Tournament.

Producers for the TV show visited the Georgia castle's company ranch in Dacula for a segment on the history of the ax.

The episode airs at 8 tonight.

Head knights Tim Baker and Brian Kennedy offered demonstrations from horseback and on foot.

"It's amazing how popular the [Middle Ages] genre has become," said Baker, Medieval Times' director of stunts and choreography. "They seem to come out with a new movie every couple of years —- 'Kingdom of Heaven,' 'Braveheart,' 'Lord of the Rings' —- we try to recreate as much as we can in jousts and sword fights."

Baker said the segment takes viewers through the evolution of the ax, from the heavy-duty weaponry of the Stone Ages to the razor-thin axes of present day.

Baker, 43, took up his sword, er, ax when Medieval Times opened its first castle in Kissimmee, Fla., in 1983.

On horseback an ax wouldn't be his weapon of choice because it's hard to stop the horse, he said. "It is extremely regrettable that one of the most popular reasons axes were used on foot was to take down a horse in battle. We just don't think like that today," he added.
