Joint christenings or naming ceremonies are the hottest thing in Hollywood right now, as the newest must-have accessory seems to be twins.

Marc Anthony and Jennifer Lopez have reportedly become the proud parents of a boy and girl, born just after midnight this morning (Friday February 22nd).

The couple's spokesperson stated: "Jennifer and Marc are delighted, thrilled and over the moon."

Earlier this week, it was claimed that People magazine is set to pay £3 million for exclusive photos of the new-borns, making it surely the most expensive baby album ever!

However, there could be rivalry for the title of cutest twins later on this year as a source close to Spin City actress Jessica Alba has revealed the star is also expecting a double dose of joy in June.

"She and Cash [Warren - Jessica's husband] have had to scrap plans for a one-baby nursery and start all over again," the mole claimed.
