Actress Jennifer Love Hewitt kept guests at her baby shower on Saturday (12Oct13) guessing about the sex of her baby by opting for a yellow and black theme.

Friends arrived at the Hotel Bel Air in Los Angeles hoping to find out whether the star's first baby with boyfriend and The Client List co-star Brian Hallisay would be a boy or a girl - but she still isn't telling.

The 34 year old and her planners decorated the party space with black and yellow balloons and signs with words like 'Giggle', 'Hiccup' and 'Crawl' were placed on easels, according to Us Weekly.

More than 30 people joined Hewitt for the shower and feasted on pizza and cupcakes, while the actress created a scent bar where her friends could mix their own fragrances.

Hewitt revealed she was three months pregnant in June (13).
