Miranda Kerr and Evan Spiegel -- Check Out the Six Pack On Us (PHOTO)

Miranda Kerr and BF Evan Spiegel were just like any other couple ... having date night at a Kanye West concert with a six pack -- oh, and he's got $2 billion in the bank.

Kerr and the Snapchat founder hit up West's concert Saturday night at the Hollywood Bowl with a sixer of Negra Modelos -- 'cause import brews are a must for Bowl nights.

They've only been together for a few months, but when she arrived at LAX before the concert ... the big 'M' came up. Check out her sly smile.
