Following her weekend getaway
with Ashton Kutcher
, Mila Kunis
has a brief stopover in Las Vegas Tuesday to promote her upcoming film Oz the Great and Powerful
at the CinemaCon Festival.
Joined at the festival by costar James Franco
, Kunis "looked cute," according to an onlooker, who noted her short skirt and heels. (Kutcher was not present
in Sin City, however.)
Later that night, Franco was spotted at Tao Asian Bistro, where he grabbed dinner with three female friends. For the meal, they enjoyed some sea bass, lobster wantons and fried rice with Chinese sausage.
