It was Joel Osteen's first wedding outside of tying the knot for a handful of family members and the pastor, who preaches to millions via television from Lakewood Church every Sunday, was endearingly nervous as he stood before the gathering of 150 that had assembled for the marriage of Dominique Sachse and Nick Florescu.

During the brief ceremony at the home of John and Becca Cason Thrash on Saturday, Osteen advised the couple of the importance of "keeping laughter in the house." Laughter, he said, serves as an antidote to troubles that the world challenges us with each day.

Stunning in a body-hugging lace gown by Ines Di Santo, Sachse responded emphatically "Oh, I do!" when asked if she took Florescu as her husband. "I promise to love, honor and respect you for all the days of my life," she repeated after Osteen. Sachse and Florescu are regulars at Osteen's Sunday services and enjoy a close relationship with the popular pastor.

The couple was attended by his children — Alex, Nicky, Ava, Ella and Isabella Florescu and Sachse's 7-year-old son Styles Credeur. They walked the rose-petal strewn aisle as family and friends cooed over the younger ones. The oohs and aahs were bountiful as Peter Sachse walked his daughter down the aisle.

What was supposed to have been a small ceremony with only 50 guests mushroomed as the KPRC Channel 2 news anchor and Florescu began compiling their guest list. The reception, which was originally planned for only 100, expanded to include 150 additional guests. When the number reached 300, hostess Cason Thrash advised that the storied indoor swimming pool would have to be covered. "I mean, there would have been 10 or 12 people in the water if they hadn't covered it and no one wants to remember their wedding like that," she said.

What everyone took home from this splendid event, beyond the beauty of and obvious adoration between the handsome couple, was the stunning collection of white flowers that covered every surface. For the ceremony, the Cason Thrash pool room was furnished like a chapel with soaring assemblages of orchids, roses, hydrangeas and more commanding either side of the wedding stage. Silver chiavari chairs with silver cushions provided seating for wedding guests. Thank you, Richard Flowers and The Events Co.

After the ceremony, while photos were taken, the wedding witnesses adjourned to the living room and bar where the schmoozing was intense and the bubbly flowed. (For the record, Osteen, accompanied by his wife, Victoria, required that no alcohol be served in his presence. Thus, the partying was closed off until the Osteens departed.)

While guests circled the towering wedding cake, by Who Made the Cake?, featuring a lace design like that in the bride's gown, a work crew streamed through the pool area turning it into a dinner club disco. In this early crowd were guests including Nina and Wayne Wickman, Roseann Rogers and Dr. Aashish Shah, Alice and Herb Butrum, Susan and Mike Plank, Annie Amante, Manfred Jachmich and Candice and Lonnie Schiller.

Waiters passed hors d'oeuvres from Katsyua while Ceron, accompanied by his partner Todd Fiscus of Dallas, regaled guests with tales of the pre-wedding hair and makeup sessions that his salon group oversaw. Debbie and Rudy Festari, Susan Glesby, Kimberly and Frank DeLape, Monsour Taghdisi and Henry Richardson and Joann and Bill Crassas were in this early crowd.

The wedding took place at 5, the second tier of partygoers began arriving at 7. At 8 p.m., City Kitchen took over and provided a lavish buffet spread that had everyone swooning. At 9 p.m., the female DJs, flown in from Paris, launched their brand of CD spins and inspired serious boogying on the dance floor at one end of the covered pool.

Among the numerous TV news personalities attending were NBC's Janet Shamlian with hubby Le Melcher, Bill Balleza, Frank Billingsley, Deborah Duncan, Rachel McNeil, Lauren Freeman and the retired Bob Nicholas.
