T-shirt and glasses, and one onlooker saw her having plenty of fun with the 'Liz and Dick' star's friend, artist Domingo Zapata.

An eyewitness told the New York Post: "Scarlett looked like she was completely flirting with Domingo."

Scarlett also hung out with actor Sam Rockwell - who arrived at the establishment following a screening for his latest movie, 'Seven Psychopaths' - but her low-key look confused many of the nightspot's revellers.

One fellow partier - whose friend had to point the blonde beauty out - said: "I didn't even recognise her."

Scarlett - who was married to Ryan Reynolds from 2008 to 2011 - appeared to be having plenty of fun without her advertising executive boyfriend Nate Naylor to the nightspot.

However, she admitted earlier this year she is in a "great" place thanks to the hunk.

The 'Iron Man' star previously said: "Everything's been really great right now. It's been a good time. I've had peace. Relative peace. I just want to work on things that are really hard, and when I'm not working on things that are really hard, I want to hang out with people I like to be with, and that's it. I think it will be an interesting year."

'The Avengers' actress - whose divorce from Ryan was finalized in 2011 after four years together - is said to be convinced he cheated on her with the 'Gossip Girl' star while they were still married and was distraught over the couple's recent nuptials.

A source told the National Enquirer: "Even though there is no evidence behind it, Scarlett has convinced herself that Ryan cheated on her with Blake.

"She's incredibly bitter about it. In a way, Scarlett feels like Blake actually stole Ryan from her, because it was when he started shooting 'Green Lantern' with Blake in 2010 that everything fell apart."

The 27-year-old actress was shocked to discover the couple had thrown a secret wedding reception in South Carolina on September 9 and was especially hurt Ryan remarried so quickly, after only a year of dating Blake.

The insider added: "Ryan and Blake's wedding has brought back a lot of pain for Scarlett. She's sure that Blake deliberately seduced Ryan, even though she knew he was attached at the time.

"On top of that, she feels like it's a huge slap in the face that Ryan would remarry this fast. Scarlett is happy and dating, but she assumed he would wait a few years before he tied the knot again."

Scarlett - who is currently romancing advertising executive Nate Taylor - has spoken candidly about her marriage to Ryan in the past.

She said: "It was a beautiful thing. The falling in love and getting married and making that commitment ... I think it's nice to know that you're capable of loving somebody in that way. I think it's a rare opportunity."
