A source for the newspaper claims that after their first date earlier this month at Chateau Marmont, Josh had sent Sienna a bouquet of flowers with a mushy note. The insider said, "Sienna guessed he was trying for old-fashion Hollywood glam with the flowers, but to her his gesture came off as unoriginal, and a little on the cheesy side. She likes her men a little rough around the edges, and Josh seems too squeaky clean."

Josh's next misstep occurred when he tried to arrange a second date with Sienna. The tattler said, "When [Josh] called her to follow up on his gift, he invited her out for a romantic dinner at The Ivy - he had already phoned the restaurant to get them a prime table. Sienna was quick to demur; she didn't want everyone jumping to the conclusion they were in a relationship."

But it's not just little mistakes that are tanking any chances Hartnett has with Miller. He's done a few things that have shown he's clearly not yet over Johansson. The Mail claims he has been talking about Scarlett non-stop to Sienna and he has even confused Sienna with Scarlett over the phone. To top it off, an insider revealed, "During one of [Sienna's] phone conversations with Josh she was gushing about what she was going to wear to the Golden Globes. Instead of saying that he couldn't wait to see the number, Josh made the mistake of saying that the outfit sounded interesting, but didn't sound like anything Scarlett would wear."
