Just hours after fans began to speculate the Keeping With The Kardashians star might be with child, her Blink-182 rapper beau made a move that only a protective daddy-to-be would.

Before their raunchy PDA session at the UFC fight night in Las Vegas on Saturday, Travis was caught lovingly putting his hand on Kourtney's stomach.

The 42-year-old was seen getting cozy with the 45-year-old drummer while waiting at Wynn Tower Suites' valet stand.

Travis couldn't keep his hands off his lady, grabbing her hands, before making the shocking move of rubbing her stomach.

Neither stars seemed to realize the paparazzi were nearby and let their guards down.

Shutterbugs got the money shot, showing Travis gently touching his girlfriend's tummy, and adding fuel to the already existing pregnancy rumors.

Kourtney was dressed to kill, wearing leather pants and a tight velour corset top.

Travis slipped into red checkered pants, a leather jacket, and, of course, his signature beanie.

His affectionate rub on Kourtney's tummy came while they were waiting for their car to take them to the Conor McGregor vs. Dustin Poirier fight.
