sunglasses smile blonde gym Nicole Richie

We love to see Nicole Richie smile!

The reality star recently received some exciting news, which is probably why she was in such a happy mood as she exited her LA-area gym, on Thursday.

Richie revealed via Twitter, "My nephew was born today, and so was Snoop. Which means he will be a SUPERSTAR!!".

The 30-year-old fashion designer also revealed on Thursday that she will be launching her very first fragrance in department stores next September.

Maybe pal Paris Hilton, who currently has 14 of her own perfumes for sale, can give Richie some advice?
