instagramBaby Kimye's coming, and pregnant Kim Kardashian could not be more excited.
The mama-to-be took to Twitter today to share an old school photo with her fans, reminiscing over three-year-old nephew Mason Dash Disick's baby days as she gears up for her own little one.
"Awwww look how little Mason was!!!" the expectant E! star wrote, posting a pic where she's playing with the adorable tot and hanging at the pool with big sis Kourtney Kardashian.
"My little Mason!!!!" Kanye West's ladylove tweeted moments later, sharing another family snapshot.
No doubt, baby Mason's cute as a button, but it's a little hard to focus on Kourt's oldest kid considering Kim's rocking a bright purple bikini in the pic and her signature booty is on full display (you're welcome, guys).
From bikinis to baby bumps, we just love keeping up with Kim!
Tune in to Kourtney & Kim Take Miami Sundays at 9 p.m. on E!
