Bryce Dallas Howard won't be following her dad's tradition of giving her baby a middle name based on where the tot was conceived.

The '50/50' star - who is in the final stages of her pregnancy - got her unusual moniker because her director father Ron Howard wanted to name her after the place she first began her life in the womb, but she has no plans to do the same with her next child.

During a panel chat for Canon's Project Imagin8ion, Bryce - who already has a four-year-old son Theo with her husband Seth Gabel - said: "It's completely gross. Thanks dad."

The 30-year-old actress' 26-year-old twin sisters, Jocelyn and Paige, share the middle name Carlyle, after the Carlyle Hotel in New York City where they were conceived by Ron and their mother Cheryl, while her 24-year-old brother Reed Cross takes his middle moniker from a London street because "Volvo isn't a very good middle name", according to the 'Frost/Nixon' filmmaker.

As part of Canon's Project Imagin8ion project, Bryce and her father Ron, 57, attended the premiere of their film 'When You Find Me' at the American Museum of Natural History in New York on Tuesday night (15.11.11).

The pair collaborated on the project which is considered to be the first Hollywood film to be based on eight independently contributed photographs.
