Keough also once starred in "The Runaways" with Pattinson's ex-girlfriend Kristen Stewart. The two have remained friends since, and Keough attended Stewart's last birthday party.
Pattinson and Keough were seen driving in Los Angeles on June 29 after picking up a ping-pong table. Meanwhile, Stewart was headed to Paris Fashion Week, furthering rumors that she and Pattinson have split for good. He has been reported to be single and "definitely over her." Pattinson and Stewart had a three-year on-and-off relationship that began its end after Stewart cheated on him with her "Snow White and the Huntsmen" director Rupert Sanders.
Keough, 24, is best known for her role as Nora in "Magic Mike." During the filming, she started dating Alex Pettyfer, who played her love interest Adam. The costars were engaged earlier this year but have since broken up. Before that, Keough dated singer Ryan Cabrera.
Pattinson and Keough may be just friends -- but spending so much time together has the rumor mill all shook up.
