Penelope Cruz the latest star on Walk of Fame

Oscar-winning actress Penelope Cruz has paid tribute to family and supporters - including her newborn baby son - as she was given a star on Hollywood's storied Walk of Fame.

In return, Johnny Depp described Cruz, who stars in the latest instalment of the Pirates of the Caribbean franchise, as an "inconceivably phenomenal mummy" and a "magical woman".

"Today is a very special day that I will always remember," said Cruz, showing off her post-pregnancy figure as she received the 2436th star on the Walk of Fame, which stretches along Hollywood Boulevard.

"Every time I look at that star, I will see the names of all the people that have helped me make many of my dreams a reality," she added.

She notably thanked her parents, brother Eduardo and sister Monica, actor husband Javier Bardem - who also attended the ceremony - and her baby son Leonardo "for making me happy every day".

Cruz gave birth to her first child in January at the Cedars-Sinai Medical Centre in Beverly Hills, but she and fellow Spaniard Bardem have kept a low profile since then.

Depp, who returns as Captain Jack Sparrow in Pirates of the Caribbean: On Stranger Tides in May, also called Cruz "as loyal and true a friend as anyone could dream of".

Cruz, 36, and Bardem, 41, met when they starred opposite each other as lusty teens in the Spanish film Jamon, Jamon back in 1992.

In 2008, they were back together on the silver screen in Woody Allen's Vicky Cristina Barcelona, for which Cruz won an Academy Award as best supporting actress.

The couple married in July last year at a ceremony in the Bahamas.
