As the most-watched celebrity designer in town, Jennifer Lopez can expect a big turnout at her clothing line’s debut at New York’s Olympus Fashion Week. PEOPLE takes a look at Lopez’s latest career design, plus other events to watch for in the coming week:

SATURDAY, JAN 29: New York Mets All-Star Mike Piazza – who once held a press conference to deny reports of being gay – ties the knot with former Playboy model and Baywatch actress Alicia Rickter in Miami. Among the guests expected to attend the intimate ceremony are Tommy Lasorda and former Mets John Franco, Al Leiter and Todd Zeile.

Tickets for U2′s Vertigo tour start selling Saturday amid a fan uproar over a presale for priority seating. Earlier this week, hundreds of fans who had paid $40 on the band’s Web site to access a special code for the Ticketmaster sale complained that they got bad seats – or none at all.

U2 promoter Arthur Fogel tells that huge demand and computer glitches are to blame, but he adds, U2 “will do whatever they can to make sure people are taken care of.” The tour, with tickets costing up to $163, kicks off March 28 in San Diego.

MONDAY, JAN. 31: Jury selection in Michael Jackson’s child molestation trial begins. The 46-year-old pop star, who also faces charges of conspiracy involving child abduction, false imprisonment and extortion, has pleaded not guilty. Last week 1,900 pages of grand jury testimony in which Jackson’s accuser details allegations of abuse were leaked to ABC and aired on Primetime. In response, Judge Rodney Melville lifted the gag order on Jackson and allowed him to do a yet-to-be aired rebuttal interview with FOX News’s Geraldo Rivera. The jury selection phase of the trial could last as long as a month. The judge ruled Friday that Jackson’s accuser, now aged 15, will have to testify in open court.

THURSDAY, Feb 3: Cast members from the retro sitcom Happy Days gather together for ABC’s two-hour 30th Anniversary Reunion of the show. The special, which includes Ron Howard, Henry Winkler, Tom Bosley, Marion Ross, Scott Baio, Erin Moran, Don Most and Anson Williams, features bloopers and recollections, plus the famous scene of Fonzie (Winkler) jumping the shark – as well as an unseen clip of the Fonz making out with Mrs. Cunningham (Ross).

FRIDAY, Feb. 4: Fashionistas will descend on New York City for the Olympus Fashion Week, and all eyes will be on Jenny from the Block as her J.Lo clothing makes its first appearance on the catwalk there. And following Jennifer Lopez’s moves backstage will be MTV, which will air Jennifer Lopez: Beyond the Runway on Feb. 24. In a statement about her fall line, Lopez said: “I am that girl who comes from the street, who comes from the Bronx, but has traveled the world and can bring all of those glamorous qualities, so it’s like a sexy street glamour.” Other big fashion names showing off their fall 2005 styles include Michael Kors, Carolina Herrera, Zac Posen and designer to First Lady Laura Bush, Oscar de la Renta.
