Stepping out for a bite to eat with her soon-to-be co-star, Sienna Miller was spotted out in New York City with Jonny Lee Miller on Monday (August 24) .

The “G.I. Joe: The Rise of Cobra” hottie looked to be having a great time with her Broadway beau, grabbing some grub at Caffe Gitane in SoHo.

As previously reported, Sienna looks to be pursuing a long-term relationship with deejay George Baker, whom she’d vacationed with in Ibiza earlier this summer.

According to Sienna’s sister Savannah (who dated Baker years ago) the two were perfectly suited for each other.

Continuing along with her non-stop promotional efforts, Sienna Miller looked pretty in purple as she visited the “Tonight Show with Conan O’Brien” on Wednesday night (August 5).

The “Layer Cake” cutie was on-hand boosting interest in her upcoming movie “G.I. Joe: The Rise of the Cobra” – which hits theaters this Friday (August 7).

During her visit, Miss Miller revealed that things got pretty hot on the “G.I. Joe” set as she worked opposite co-star Channing Tatum.

“I burned my boobs in an explosion that went wrong,” Sienna told Conan, adding, “They’re fine. Let’s not grunt on it.”

At the beginning of the year, her affair with Balthazar Getty went public, and now Sienna Miller admits she has regrets.

The “Alfie” star recently told British GQ, “The situation I got into was not ideal, but it happened and if I could go back and be more responsible, I would."

She confesses that the relationship "probably looked awful," adding "I probably seem like not a particularly nice person, not a girl’s girl."

A positive side to the whole thing? Miller believes she’s grown up a lot since then and she’s ok being alone. She tells, “I haven’t been living with anyone or been in a proper relationship, and it’s been really great."

Stepping out for her all-important promotional duties, Sienna Miller presented the new fragrance “Boss Orange” by Hugo Boss in Madrid, Spain on Friday (June 5).

The “Factory Girl” actress playfully posed with the brand’s latest line, hamming it up for photographers at the El Corte Ingles store.

Keeping up her look, Sienna Miller was spotted getting her eyebrows done at Anastasia salon in Beverly Hills, California on Friday (May 29).

Wearing a striped Chanel top with rolled up jeans and black kicks, the “Layer Cake” cutie was all business as she quickly walked past on looking paparazzi.

Meanwhile, Miss Miller recently chatted with press about the horrific experience of handling a gun while filming “GI Joe” – in which she plays The Baroness.

Sienna said: “It was scary. I got taken away from the group! They said, ‘Sienna, you’re a villain in this film and you look like you’re terrified of the gun.’ And I said ‘I am!’ But we were shooting live ammunition that could kill someone.”

Gearing up for yet another flight across the pond, Sienna Miller was spotted arriving at LAX International Airport yesterday (May 15).

The “Factory Girl” hottie looked a bit annoyed with the paparazzi as she exited her car and made her way inside the terminal to catch a British Airways flight to London.

In related news, it seems an indie director has taken not of Miss Miller’s acting prowess and is offering her a role in a new movie called “The Dreaming Spires.”

Shamim Sarif, the director and writer of the flick, describes the plot as centering on a young student who falls in love with a blind, married English professor in her thirties.  Filming is due to start this fall.

So are Balthazar Getty and Sienna Miller taking their affair, now relationship, to a whole other level? Getty and Miller were spotted viewing an LA estate together recently. Maybe the lovebirds are moving in together?

The Mirror UK is reporting that Sienna Miller and her married boyfriend, Balthazar Getty, are looking for a home together just months into their relationship.

The luxury mansion is in LA’s Trancas Canyon in Malibu, and carries a very hefty price tag. The home has four bedrooms and six bathrooms. The area also has quite a few celebrities in the neighborhood.

Angelina Jolie and Brad Pitt used to live in that area, and Leo DiCaprio and andy Garcia have homes there.

The exclusive Trancas Canyon is very private, which appeals to the celebrities. And something Sienna and Balthazar will need after their affair has blasted across the world.

Sienna Miller’s reputation has really taken a hit after the affair was exposed. Miller has lost fans, and even had her London home vandalized with “Slut” written on the exterior.

Not to ruin Miller and Getty’s happiness, but makes you wonder how Rosetta Getty and the kids are getting along?
