Princess Charlene Of Monaco Shows Off Tiny Baby Bump

She's got that glow!

Princess Charlene of Monaco couldn't contain her loveliness when she stepped out with hubby Prince Albert this week for the annual picnic in 'Le Parc Princesse Antoinette' in Monaco—giving the public another glimpse of her growing baby bump.

Charlene, who is pregnant with her and Albert's first child (the prince also has two other children out of wedlock), looked gorgeous in a navy blue zip-up dress that flattered her growing belly.

Although she looked radiant, the 33-year-old former Olympian may have been feeling a bit protective of her bump, as she was seen clutching a bouquet of flowers to her stomach.

The couple are expecting their child at the end of the year. They have not yet released whether they are having a boy or a girl.

So far, Charlene's maternity style has been on-point, and she can probably thank another princess, Kate Middleton, for inspiring some of her choices.

Like the Duchess of Cambridge, Charlene has been sporting classic looks that could easily be worn by those of us who are not with child.

Charlene is stunning:
