Well, see, they're celebrities.

And real big ones at that. She's an Oscar-winning actress; he is the frontman for one of the biggest pop acts in the world.

Which is why it should come as no suprise that Gwyneth Paltrow [Images] and Chris Martin (of Coldplay) have straddled their newborn son with a peculiar name.

After all, they already had a daughter named Apple.

On Monday, Gwyneth gave birth to a healthy baby boy, and the couple announced he will be called Moses.

That's right, Moses Martin it is.

The playground-unfriendly name is apparently a result of a song Martin wrote for Gwynnie a couple of years ago by the same name, with words like 'Like Moses has power over sea, so you've got power over me ... You're a refuge, somewhere I can go. You're air that, air that I can breathe, 'cause you're my golden opportunity.'

Well, rock stars have traditionally always given their kids weird names. David Bowie called his son Zowie (yes, making it Zowie Bowie!); Keith Richards called his daughter Dandelion; Bob Geldof's daughters are called Fifi Trixibelle, Peaches Honeyblossom and Pixie; Frank Zappa's kids are called Moon Unit, Dweezil and Ahmet; and Michael Hutchence named his daughter Heavenly Hiraani Tiger Lily.

But as rock legend Zappa once said, 'People make a lot of fuss about my kids having such supposedly 'strange names', but the fact is that no matter what first names I might have given them, it is the last name that is going to get them in trouble.'

Keep that in mind, Moses.
