Aw! North West Has Gotten So Big—See Kim Kardashian and Kanye West's Little One at the Airport!

Mother and daughter duo appeared to be in good spirits as they went through security

What a face!

Kim Kardashian and the always adorable North West made their way to the East Coast just in time to spend Valentine's Day with Kanye West.

The mother-daughter duo was seen going through security at LAX late Thursday evening.

And look how big the couple's bundle of joy has gotten! Nori appears to be growing fast and looking a lot like her famous mama these days. We can't get enough of those cheeks!

Baby North was wearing a cozy gray onesie while her mama carried her through the lines.

Meanwhile, Kim looked as glamorous as ever with her newly dyed brown locks and a fur-lined coat.

The 33-year-old was seen pushing her daughter's stroller through the terminal before stepping onto the plane.

She tweeted early Friday morning, "Nothing better than being with my love on Valentine's Day!"

The rapper performed at Pennsylvania State University last night for his Yeezus tour.

West thanked his fans for braving the extreme winter weather in a statement, saying, "I'd like to thank everybody that came out tonight in the snow. I really thank y'all for coming and supporting tonight."

He added, "I hope I didn't keep y'all too long tonight…playing all these records. Talking all that truth. I couldn't be standing here right now if it wasn't for all of y'all supporting me all these years. Screaming on people on my behalf. Like y'all in my family."

Sounds like Yeezy is starting out the romantic holiday on a grateful note!
