MOSES JOINS APPLE: It's a boy for Gwyneth Paltrow and Chris Martin.

Moses Martin, the couple's second child, was born during the weekend in New York City, the office of Paltrow's publicist, Stephen Huvane, said Monday. No other information was being released.

Paltrow, 33, won an Oscar for her role in 1998's "Shakespeare in Love." The British-born Martin, 29, is lead singer of Coldplay.

Their daughter, Apple, will be 2 on May 14.

After Apple's birth, Paltrow appeared on "The Oprah Winfrey Show" and said she didn't understand why people were making a big deal about her daughter's name. Paltrow said it was Martin who came up with Apple.

"It conjured such a lovely picture for me -- you know, apples are so sweet and they're wholesome and it's biblical -- and I just thought it sounded so lovely and clean," Paltrow told Winfrey.

REBA TO HOST MUSIC AWARDS: Reba McEntire has been selected to host the 41st annual Academy of Country Music Awards, set for May 23 at the MGM Grand Garden Arena in Las Vegas. The show will be televised live on CBS.

This year's telecast will be McEntire's eighth turn as host of the ACM Awards. In her career, she has won 11 ACMs, including eight top female vocalist trophies, making her the all- time leading winner in that category. She has been nominated for a total of 41 ACM Awards.

In a prepared statement, ACM executive director Bob Romeo called McEntire ``the leading lady of this organization'' and ``the face of the <WC>a<WC1>cademy<WC>.<WC1> ... Her wit, comic timing and her relationship with the artists bring a dynamic to the awards that ... is unprecedented in our industry.''

`IDOL'-IZING REGIS: Regis Philbin said there should be a celebrity edition of ``American Idol,'' and he would try out for it.

``And if I don't win it, there's something wrong,'' he said during an appearance Friday at the opening of an interactive, ship-shaped museum dedicated to the Titanic disaster.

Philbin, who has released two successful albums in the past two years, was responding to a challenge from Randy Jackson, an ``Idol'' judge who sat in for Philbin on ``Regis and Kelly'' on Friday.

Philbin and his wife, Joy, were in Branson, Mo., to christen the ``Titanic: The Legend Continues'' museum. Philbin, 74, also performed Friday night at the city's Grand Palace.

NO MORE DOGGED DEVOTION: Bow Wow and Ciara have split, a spokeswoman for Ciara has confirmed. The young celebrity couple had dated for nearly a year.

``I cannot comment on the reason, but can confirm that Ciara and Bow Wow have split,'' said Tracy Nguyen in a statement Monday. The spokeswoman also took the unusual step of stating that the breakup wasn't amicable.

A message left with Bow Wow's publicist wasn't immediately returned.Bow Wow, whose real name is Shad Moss, was christened Lil' Bow Wow by Snoop Dog. He dropped the ``Lil''' in 2003.

The 19-year-old rapper sang a duet with Ciara on ``Like You,'' the second single off his fourth album, ``Wanted.''

Ciara, 20, was dubbed ``the First Lady of Crunk & B'' by Lil' Jon, who produced her debut single, ``Goodies,'' from her 2004 album of the same name.

IN DAD'S FOOTSTEPS: It appears Patrick Schwarzenegger may be going into the family business - show business, that is, not politics. The 12-year-old son of Gov. Arnold Schwarzenegger (known to have sold a few movie tickets himself) has a small part in ``The Benchwarmers,'' the feature that opened in theaters on Friday starring Rob Schneider, David Spade and Jon Heder as a nerdy bunch who challenge several kids' baseball teams for bragging rights and a little emotional healing from their tormented childhoods. Patrick plays ``jock kid, game #3,'' a part that in itself wouldn't get him a powerhouse agent. But it was enough to attract mom Maria Shriver, sisters Katherine and Christina, and brother Christopher to the premiere April 2.
