Katy Perry delighted fans when she shared a photo alongside her older sister, Angela Hudson, on Thursday and they sported two very different looks.
The singer was celebrating her work with charity, Baby2Baby, and posted several photos to Instagram, including one alongside her sibling - but they're far from lookalikes.

While some of Katy's fans said they shared the same smile and pose, many commented that they didn't realise they were sisters.
The star explained what they were doing in the caption which read: "So honored to join the coolest club of being an Angel for @baby2baby! Becoming a mother made me aware of the many everyday needs of our beautiful blessings and how sometimes those needs are hard to meet for some families.
