Scarlett Johansson is now single again after breaking it off with beau Nate Taylor and is being touted as “one of the most eligible women in the world”.

The 27-year old actress has been dating the ad exec since at least February, and the two were seen on a Hawaiian vacation together but weren’t photographed with one another very much. While some think she was just keeping a low profile after her split with Sean Penn, others wonder if she just wasn’t very serious about Taylor, especially after she was spotted in June with Bradley Cooper.

“The chemistry between them was VERY evident and they looked totally wrapped up in each other — very cute! They were definitely having more than a ‘friends’ dinner, it seemed pretty obvious they totally have the hots for each other,” a source told RadarOnline.

Others are speculating that life in the public eye had begun to take a toll on Taylor; Johansson addressed the difference in their lives in Vogue, however, saying he had adjusted to it well.

“It’s totally bizarre. It’s an adjustment — I mean, it’s got to be an adjustment for him way more than it was for me at nineteen. But he’s remarkably good about it.”
