Ben Affleck, Sienna Miller spark rumors by holding hands

LOS ANGELES, Dec. 11 (UPI) -- Ben Affleck and Sienna Miller sparked speculation on the set of Live by Night this week.

The 43-year-old actor and 33-year-old actress sent fans into a frenzy by appearing to hold hands between takes on the movie's set in Los Angeles. Both Affleck and Miller split from their respective partners, Jennifer Garner and Todd Sturridge, this year.

Sources told E! News dating rumors may be premature, saying, "He is directing her and his movie -- a movie in which he stars in. So while they not only share scenes, he directs her ... No one seems so be interested in those photos with him and his male co-stars."

"There are no signs of romance between them," an insider added to People magazine. "He has had some special scenes with Sienna, including kissing scenes. They seem to get along great, but Ben has acted very professional."

Affleck and Miller portray love interests in Live by Night, which is based on the Dennis Lehane novel of the same name, and opens in theaters in 2017. The actor was also spotted on set with a massive back tattoo, which sources told TMZ is 100 percent real.

Affleck and his wife, Garner, who share 10-year-old daughter Violet, 6-year-old daughter Sera and 3-year-old son Sam, announced their intent to divorce in June. Miller and partner Sturridge split in July. They share 3-year-old daughter Marlowe.
