"They're still friendly," an insider revealed of the pair. "It was never really serious."
Will and Arielle first started dating in January and made their public debut as a couple at a Golden Globes after party on Jan. 11. "She loves to laugh. The past few girls haven't been fun enough for him — he's a child at heart," another source said of the duo.
