But we shouldn't really call it a walk of shame, because X17online can report exclusively that Khloe Kardashian drove herself to French Montana's house! And not only that, but when she left around 10am this morning, she was wearing a different outfit -- clearly she had this whole thing planned!

On Thursday night the Kardashian family dined at Cecconi's to celebrate pal Scott Cunha's birthday, and after hanging with her family for a bit, Khloe and French returned to his Los Angeles home.

A photographer on the scene tells X17online:
    " Khloe must really not want this to get out -- she parked IN his garage so her car wouldn't be seen. Maybe she's trying to keep this sleepover on the DL so Lamar doesn't find out."

The duo partied with Scott Disick on Wednesday night at Hooray Henry's, and last Friday French accompanied Khloe to Diddy's son's sweet sixteen bash at 1Oak. Khloe was joined by little sisters Kendall and Kylie at that event, so clearly he's spent quite a bit of time with her family over the last week or so.

From leaving comfy clothes at his house to introducing him to her inner circle, it sounds like things are getting super serious! But maybe next time French will come to Khloe's Calabasas crib so she doesn't have to drive all the way back from his pad in the Hollywood Hills? She looked a little tired when we caught her heading home today:
