Kim Kardashian's maternity looks just keep getting sexier!  

The "Keeping Up With The Kardashians" star stepped out on Monday and displayed some serious cleavage while on her way to Craig's in West Hollywood.  

The 34-year-old was chic in all black with a Margiela blazer, Proenza Schouler fringe skirt, a nude bodysuit and Tom Ford lace-up heels. She kept her hair pulled back in a long sleek ponytail and accessorized with a black choker and clutch.

The sighting comes after the mom-to-be tweeted about her growing stomach earlier in the day -- telling her fans, "I'm at the stage now where I wake up with a flat belly but then as I eat and by the end of the day it pops out! This means it's about to pop."

The brunette beauty, who is expecting a boy, is about four months along with baby number two and has continued to rock her super sexy style.

North West's mom has worn everything from sheer dresses, to crop tops and various curve hugging ensembles.  

The reality star was spotted out over the weekend in another fashion forward look for a movie date with her 2-year-old daughter and hubby Kanye West.  

The "Selfish" author and the adorable tot matched in coordinating neutral looks with Kim in a skin-tight dress, Lanvin coat and lace-up heels.

But it looks like little Nori, who was enjoying some popcorn, managed to get some grease on her mom's $4,500 couture piece!
