Ashton Kutcher and former That 70's Show costar Mila Kunis were spotted spending Sunday together in LA. They were seen shopping for furniture and later dining on sushi at Asanebo. Witnesses say that the former TV couple looked pretty cozy together. 

Mila's rep says the rumors are not true. The two are just friends and have been for years. There's "definitely nothing going on there" and the rep says that there were three other people out to dinner with them.

Meanwhile: Ashton's ex-wife, Demi Moore, has returned to Twitter. She disappeared from the site after their split, but Sunday posted a photo of herself with the caption "testing". She still uses the handle @MrsKutcher...at least for now.
