Lady Gaga found performing in a dress designed by her sister a "joy".

The 29-year-old star had a number of costume changes during her concert at the Hollywood Bowl in California with Tony Bennett on Saturday but her favourite was a pink gown adored with a giant bow at the waist which had been created for her by younger sibling Natali Germanotta and her costume designer Perry Meek.

She tweeted alongside a photo of herself in the dress: "What a joy singing La Vie En Rose in a dress made by my sister Natali Germanotta & Perry Meek @aussiegearla (sic).

The 'Telephone' hitmaker donned a number of spectacular sequinned creations for the concert and stunned the crowd with a particularly daring red sheer-bodiced halter dress with a feathered skirt, which she wore during 'I Can't Give You Anything But Love'.
