New York City today will see two massive storms touch down - Bieber fever and gay-courting Obama.

Justin Bieber, a teen idol who released a new fragrance package called Someday, will hit the midtown Macy's at 2:30 p.m., to meet his fans and take photos with the first 325 who purchase the $135 perfume package.

Bieber fever has hit New York City way earlier than Thursday, with frantic tweens camped outside the store since 7 a.m. Tuesday.

With Justin Bieber's appearance at the store, the number of fans to hit the midtown will far exceed 325.

Considering the near-riot caused by Bieber's scheduled appearance at a Long Island mall in 2009, Herald Square could easily be flushed with throngs of screaming teens, amNewYork said. NYPD escort cars were seen at the scene this morning, getting ready for the heat wave.

Meanwhile, President Barack Obama will be landing at JFK airport at 5 p.m., Thursday to host a LGBT annual gala in the epicenter of New York State stuck on the same-sex marriage bill.

Obama will first attend a $1,250-a-ticket dinner hosted by Neil Patrick Harris at the Democratic National Committee's LGBT Gala. Then he will head to a $35,800-a-plate dinner at Daniel on the Upper East Side 65th Street, followed by a fundraising performance of Sister Act at the Sheraton hotel at Seventh Avenue and 53th Street.

White House officials say not to expect any new stance from Obama at the Thursday evening event, where as many as 600 guests were expected to attend, according to the Associated Press. The developments in Albany, the state capital, make it likely that Obama will have to address the issue before a roomful of supporters described by the Democratic National Committee as allies of the lesbian, gay, bisexual and transgender community. It was to be his first fundraiser geared specifically toward the gay community, the Press reported.

In October 2010, Obama declared his evolving position in same-sex marriage, saying he was wrestling with the issue. I think that it is an issue that I wrestle with and think about because I have a whole host of friends who are in gay partnerships. I have staff members who are in committed, monogamous relationships, who are raising children, who are wonderful parents. And I care about them deeply, said Obama in an interview at the White House.

New York awaits some real storms today. Unless you want to be swamped by the massive wave of teens screaming and swooning, beware of midtown this afternoon. Likewise, watch out for gay protesters around Obama.

If you are attending one - or more - of these events, have fun. We wish your safety.
