Whoa! Tammin Sursok is a pretty pregnant little liar! 

The expecting Pretty Little Liars star looked gorgeous in a itsy-bitsy teeny black bikini — which showed off her growing baby bump! — during a recent trip to the beach with hubby Sean McEwen. Tammin and Sean soaked up the California sun with a relaxing boat ride along the coast. With that bikini bod, we'd be all smiles too, Tammin! 

Tammin announced her pregnancy in June, and we've been over the moon for the excited mom-to-be. While she’s kept relatively private about her baby, she recently took to Twitter to reveal a big secret. It turns out that Tammin knows the sex and name of her pretty little baby! But not so fast, PLL fans. Tammin isn't ready to reveal such private information (she is like Jenna, after all!). 

"Guess what? I know if it's a boy or a girl and I know the name ....got a secret.. Gotta keep it......;)" she tweeted in June. 

Aw! Well, we're just happy she shared another cute baby bump pic for us to swoon over! 

Are you happy for Tammin and her hubby? Plus, how good does Tammin look in the black bikini?! Sound off in the comments!
