At the Baby2Baby Gala in Los Angeles on Saturday Katy Perry flaunted her big cleavage and threw a storm.

Katy stood for a dazzling group that was once filmed with celebrity mothers Kate Hudson, Jessica Alba, Chrissy Teigen and Kelly Rowland.

"Finally, you can add to my CV" Helps to give birth to babies in living rooms! "It was a miracle of the day … Aunt Katy aka Stylist Aunt," Katy tweeted in 2014.

Katy, who will make her second marriage when she ties the knot with Orlando, currently has no children.

She was briefly married to Russell Brand, with whom she had a Hindu wedding in a tiger sanctuary in Rajasthan in 2010 – the same state in India where Priyanka Chopra had married Nick Jonas last December.
