Unknown plant

I was given a succulent cutting. I have no idea what the name of the plant is. It developed a flower bud and they grew longer and longer (about 7 to 8 cm) before opening up to these lovely star shaped flowers. The plant has a greyish variegated leaf

How pretty- if it's not named after some sort of star, I'd be really surprised because it really does look like one. Nice shot!
