Kourtney wasn't acting like a Kardashian when she stepped out with the Blink-182 drummer on Monday night in Los Angeles, just hours after returning home from their whirlwind trip to Las Vegas.

Covering up her curves, the oldest Kardashian sibling slipped into a pair of black sweats and wore a baggy t-shirt on top.

Keeping it casual, Kourtney opted for sneakers instead of her signature heels and concealed her face as she flew past photographers.

Travis held onto his girlfriend with a tight grip as she buried her face in his arms, avoiding flashes and money shots -- something she and her sisters are usually hungry for.

Unlike Kourtney, Travis kept his head held high and guided his reality TV show girlfriend away from the shutterbugs.

Wearing a red t-shirt, black jeans, and Converse, the rocker flaunted his tattoos while Kourtney hid her entire face and body.

It's an interesting move since the couple sparked pregnancy rumors just days ago.
