The Girls actress and the “Cheap Thrills” pop superstar were spotted out and about together on Wednesday (July 11) in Los Angeles.
At one point on their outing, Lena seemed to present a surprised looking Sia with a ring on her right hand outside of Dune restaurant.
Lena recently opened up about her weight and why she’s happier now than when she weighed 24 pounds less last year with a photo comparison on Instagram.
“Even this OG body positivity warrior sometimes looks at the left picture longingly, until I remember the impossible pain that brought me there and onto my proverbial knees. As I type I can feel my back fat rolling up under my shoulder blades. I lean in,” she captioned the post.
