Demi Lovato and the Jonas Brothers performed at the Houston Livestock Show & Rodeo before soon after heading back to Los Angeles, CA to attend Oscar after parties and events. I have added photos of the event to the gallery. Enjoy!

Tween (and teen) spirit — literally — lit up Sunday’s sold-out RodeoHouston show featuring the Jonas Brothers and Demi Lovato.

Red, blue and green glowsticks whizzed through the air. Cameras flashed nonstop. Toothy smiles were everywhere. The energy was contagious.

Dallas-born Lovato took the stage first for a four-song set, and she was clearly excited to be back in Texas.

“There are so many people out there. My hearts about to burst through my chest,” she tweeted just a few minutes before taking the stage. “I’m so ready for this!”

Lovato looked stylish in all black, including strategically ripped pants; and she seemed sweet and sincere. But her voice often cracked and was weak in several places. At times, she was completely inaudible, and there was a lack of strong backup vocals. [REMEMBER SHE IS SICK THOUGH!!!]

Despite those flaws, Don’t Forget boasted terrific buildup and release. And Lovato found her footing a bit during Here We Go Again (though she yelled much of the song).

The Jonas Brothers started quietly with Lovebug, which still incited equal doses of screams and singalong. Every minor movement, in fact, earned ear-piercing cries. It’s the same excitement that greeted the sibling trio’s 2009 RodeoHouston debut.

The madness hit a frenzied pitch when Joe, dressed in a form-fitting designer suit, jumped offstage and leapt onto the nearest railing — just inches from the outstretched hands of breathless girls.

The JBros have grown since their days opening for Miley Cyrus. They’re more playful and confident onstage. Vocally, all three also showed marked improvement (save for a wobbly When You Look Me In the Eyes).

Early single Year 3000 is still a fizzy jolt of pop silliness, and Lovato (in much better voice) returned to duet with Joe on This Is Me, a song from the Disney film Camp Rock. (The pair also debuted new charity tune Make a Wave.)

Extra touches also made the set spirited and fun. Nick took a solo turn during Who I Am, and all three brandished cowboy hats (and twangy accents) for a cheeky cover of Keith Urban’s Somebody Like You.

By the end of the set, when the JBros powered through hits SOS and Burnin’ Up, it was useless to resist the rush of rocket-fueled pop.

Demi Lovato offers up a great big smile as she waddles out of a nail salon with pedicure flip flops on her feet in Studio City, Calif., on Wednesday afternoon (March 3).

The 17-year-old songstress took a break from filming season two of Sonny With A Chance with a little me-time.

Demi Lovato and Joe Jonas sing “Make a Wave” live in Epcot at Walt Disney World
February 11, 2010

Make A Wave, an inspirational duet by Hollywood Records recording artists and Disney Channel stars Joe Jonas and Demi Lovato, recorded for Disney’s Friends for Change: Project Green and to be featured in the upcoming Disneynature film OCEANS, was unveiled today in an exclusive performance during the Celebrate Family Volunteers event at Walt Disney World® Resort in Lake Buena Vista, FL. The anthem will debut February 26 on Radio Disney, while the music video will have its world premiere on Disney Channel March 14 and launch online the following day at Disney.com. Make A Wave will be available beginning March 15 on iTunes, with all proceeds benefiting environmental charities through the Disney Worldwide Conservation Fund (DWCF). OCEANS hits theaters April 22, 2010 (Earth Day).

With the motivating lyrics just a pebble in the water can set the sea in motion, a simple act of kindness can stir the deepest ocean, the anthem carries the main message of Friends for Change: when people work together, small steps can add up to a world of difference. With its water theme, the song also helps to underscore the importance of protecting the worlds water habitats, which make up nearly three- quarters of our planet.

Make A Wave is the follow-up to last years hit Friends for Change anthem Send It On by Miley Cyrus, Jonas Brothers, Selena Gomez and Demi Lovato. To date, Send It On has helped raise more than $500,000 for conservation projects across the globe. A large portion of those funds is helping revitalize forests in the U.S., Latin America and Europe in collaboration with Arbor Day Foundation. Proceeds are also being directed to the Disney Worldwide Conservation Funds Rapid Response Fund which focuses on aiding animals affected by disasters. As a recent example, $20,000 was directed to the International Fund for Animal Welfare, a leading member of the Animal Relief Coalition for Haiti, working to provide care for animals following the devastating earthquakes.
