Tom Cruise and Katie HolmesTom Cruise and Katie HolmesHave Tom Cruise and Katie Holmes stumbled upon a name for their unborn bubby?

Possibly...

The Hollywood couple seem to have promised talk show host Ellen DeGeneres that they'll name baby Cruise in her honour.

They said they'd call the tot Dellen Cruise, after Ellen offered to help them out as a babysitter.

Tom and Katie were guests on Ellen's show when she offered her babysitting services for free.

She said: "Send it over because, babysitting, I think is like $12.00 an hour. And they will take advantage of you for like $15.00."

How generous, Ms Degeneres.

Of course, we're not taking it as read that this will really be the name that the couple choose.
