The 30-year-old "Poker Face" hitmaker was driving her red Ford F-150 SVT Lightning pickup truck on a highway in Malibu, California and got pulled over, reported Entertainment Weekly.
"Ya I got pulled over. Big deal! I just haven't received plates yet for my new pick up!" Gaga tweeted
It is unclear if she was issued a ticket.
The singer had shared her excitement over getting her license on social media, sharing a pic of herself in her truck, with a friend, as well as photos of her smiling while sitting at a desk after taking the written test at the DMV and embracing the ground after passing her road test.
