Zellweger admits fears for Bridget accent

American actress Renee Zellweger was petrified she wouldn't be able to master her celebrated British accent in the sequel of her hit movie Bridget Jones' Diary.

The blonde beauty depended on a 24-hour voice coach to ensure her 'Sloaney' voice didn't disappoint fans in romantic comedy Bridget Jones: The Edge of Reason, co-starring actors Hugh Grant and Colin Firth.
