On Friday night, Lady Gaga and Bradley Cooper went out to dinner in LA. What might have been a relatively innocuous outing — though it's a surprising pairing, we'll admit — got more interesting when Bradley rolled up on a motorcycle with Gaga on the bike behind him. We last spotted Lady Gaga in Palm Springs in her bikini at the beginning of the month, while Bradley looked adorably smitten with Irina Shayk in NYC back in March. Luckily for us, the two converged for one mysterious nighttime adventure. Check out the pictures from their outing, and then find out everything we know about Gaga's impending nuptials with Taylor Kinney.
