Zoe Saldana isn't hiding her relationship with Bradley Cooper anymore.

The Avatar actress gassed up her beau's Mercedes G-Wagon in Brentwood. What a thoughtful girlfriend!

Wearing black pants and a blue and white polka dot sleeveless blouse, Ms. Zaldana flaunted her super skinny arms while holding on to the pump.

Perhaps Bradley will take his ladylove to the gym in the near future to pump up her biceps. With Avatar 2's production beginning this year, Zoe needs to build her strength STAT!
