Bradley Cooper was spotted taking a break from filming in London as he went for a stroll in a leather jacket and black t-shirt.

Britain's Prince William photobombed a picture of Chris Hoy at the Commonwealth Games yesterday (29.07.14).
The 31-year-old royal managed to quickly jump into the background of the snap as the former track cyclist posed at the event in Glasgow, Scotland.
Chris, 38, posted the blurry image on his Twitter account last night, which he accompanied with the caption: "Got to love a royal photobomb!"
It seems William - who has 12-month-old son Prince George with his wife Duchess Catherine - is following in his brother Prince Harry and grandmother Queen Elizabeth's footsteps as they both snuck into the background of different photos as well last week.
Harry, 29, flaunted his pearly whites as he grinned behind three New Zealand rugby coaches, Sir Gordon Tietjens, Trevor Shailer and Gary Hermansson, as they smiled for the camera at the 800m women's swimming freestyle on Monday (28.07.14).
Harry's funny photobomb came just four days after Elizabeth, 88, found herself in the background of Australian hockey player Jade Taylor and her teammate Brooke Peris' self-taken snap last Thursday.
The picture - which Jade, 29, posted on her Twitter account - shows the girls smiling at the camera while the Queen, dressed head to toe in mint green, can be seen grinning at the pair behind them in the shot.
She captioned the image: "Ahhh The Queen photo-bombed our selfie!! #royalty #sheevensmiled #amazing #Glasgow2014 @Hockeyroos @AusComGames (sic)".

Britain's Prince George "loves the water."
The 12-month-old royal has been having swimming lessons with his mother Duchess Catherine, 31, and the brunette beauty told former world champion James Hickman at a SportsAid charity meeting on Monday (28.07.14) the tot enjoys splashing around in the pool.
James, 38, told the Express newspaper: "She was at the [Commonwealth Games] swimming [event] last night, so I was just interested to know if she had taken George swimming.
"Hopefully if they can get him swimming he could be a future international swimmer.
"She's been swimming with him. She said he loves the water and he grabs things to splash with.
"So, maybe he could be the next royal to take part in the Olympics and if he was in swimming that would be incredible."
Meanwhile, Prince William, who married Duchess Catherine in 2011, previously admitted that he would like George to learn how to scuba dive.
Speaking as the new president of the British Sub-Aqua Club, William, 31 said recently: "I hope my son George will also learn with the club but, at the moment, bath time is quite painful. But, as he gets older, I imagine donning a mask and snorkel might calm him down."

Britain's Prince Harry does boxing to stay in shape.
The 29-year-old royal revealed he does the sport at home to help improve his fitness levels after going against Declan Gilmour, who has been boxing for four years, during a visit to Gorbals Leisure Centre in Glasgow, Scotland, yesterday (29.07.14).
Declan told the Daily Mirror newspaper: "He actually beat me 3-2 on shoulder taps and I was trying hard... He was actually saying he has been doing boxing training back home. He just uses a punch bag and was saying he wanted to get in better shape."
The flame-haired hunk was joined by his brother Prince William as they met youngsters taking part in the Coach Core programme, which they launched last year.
Harry also surprised Nathan Bawuah, 21, an apprentice coach from London, after they went head-to-head in a boxing match, which ended in 2-2.
Nathan said: "He was very nimble. I didn't expect that. He was so light on his feet, really agile.
"He made me sweat so much. I haven't moved like that in such a long time."
While Harry was busy showing off his boxing skills, William, 31, had a go at playing some soccer.
Before their visit ended, the brothers both took part in a five-a-side soccer match, which saw Harry's team win after he set up Lauren Weir, 21, with a pass to score the only goal of the game.

Jessie J thinks 'The Voice' viewers need to vote on talent alone.
The 26-year-old songstress - who appeared as a coach on the hit show for its first two series - says gifted singers are often voted out early on the singing competition because the audience "forgets it's about the talent" and vote for their favourite.
She explained to the Metro newspaper: "It just takes one person to make the show happen. If that person gets kicked out too early it can ruin it. The show brought out some amazing talent. Ash, who was on my first team, is, as far as I'm concerned, the best singer that's ever been on - but he didn't get through and I couldn't help that.
"The public need to think about whose album they'd buy rather than whose trousers or back story they like.
"Viewers get to know the contestants so well you forget it's about the talent."
The 'Bang Bang' singer also ruled out a return to the judging panel at the moment because she's so busy working on her new album.
Jessie said: "I've had no discussions about it. I don't have time to do a TV show when I'm putting out an album - which is what I tried to do with album two. The contestants deserve someone with the time and dedication they need. Never say never but I haven't been asked back. Or maybe I have and my manager hasn't told me. I'd like to think they'd ask me back."
The singer then quipped: "I might just buy a chair from Ikea and do it with Instagram videos at home!"

Robert Pattinson's sister has wowed the judges on 'The X Factor'.
Singer Lizzy Pattinson has already made it through the first round of auditions, which take place behind closed doors, and is expected to perform for Simon Cowell and co. once again this weekend at London's Wembley Arena.
A source said of her audition: "She blew them away with her husky, soulful vocals. She's different to usual 'X Factor' contestants - she really stands out. She could go all the way."
The 31-year-old singer has provided backing vocals on songs for various 'Twilight' soundtracks and even had a top 20 hit in the UK in 2003 with club song 'Let the Sunshine In'.
But Lizzy is said to be wary of being associated with her world famous sibling, Rob, 28, and is eager to succeed on her own merit on 'The X Factor'.
An insider told the Daily Mirror newspaper: "She didn't mention she was related to him to any judges or producers. It's important to her she does not fall into the trap of just becoming 'Rob's sister'."
It's thought Lizzy is a "shoo-in" to progress on the show after her first audition proved a hit with Simon, Cheryl Cole, Louis Walsh and Mel B.

Mark Wright had a "vicious" row with best friend James 'Arg' Argent and his cousin Elliott Wright at a family wedding.
The former 'The Only Way is Essex' star reportedly clashed with the the pair at his cousin Leah Wright's wedding in Alicante, Spain, earlier this month after the hunk and mum Carol demanded that his sister Jessica Wright had a go at singing on stage instead of Arg.
An insider said: "Other people at the wedding were shocked at how vicious things got and couldn't believe what they were seeing."
But fans of the ITV2 reality show hoping to see the argument on the programme will be left disappointed.
'TOWIE' bosses were not allowed to film Mark and his fiancée Michelle Keegan at the nuptials because he is no longer contracted to the show since departing in 2012 at the end of the third series.
The insider added to The Sun newspaper: "But while Mark and Michelle were at the wedding the whole time, producers couldn't film them and had to act like they weren't there."
Viewers of the programme saw part of the row when Arg and Jess clashed on Sunday night's (27.07.14) show, but Mark and Michelle were nowhere to be seen.
The 27-year-old star was one of the original cast members on the programme when the show started in October 2010.
He has since gone on to star in 'I'm A Celebrity... Get Me Out Of Here!' and land TV shows including 'Mark Wright's Hollywood Nights' and 'Party Wright Around the World'.

Mary Berry won a burping competition whilst filming 'The Great British Bake Off'.
The BBC cooking show has earned plenty of fans due to its wholesome content and family friendly bakes, but the show's stars are less than exemplary behind the scenes, it seems, as they often take part in belching contests.
Presenter Mel Giedroyc revealed how judge Mary, 79, beat her, co-host Sue Perkins and fellow judge Paul Hollywood in one gassy burp-off.
She joked to Woman magazine: "I thought I'd clinched it but then Bezza came out with a long, loud one, and pipped me to the post. She's brilliant."
The fifth series of the hugely popular baking programme is set to start on August 6, moving to BBC One after launching on BBC Two in 2010.
Twelve contestants will be fighting against soggy bottoms and overworked pastry in a bid to impress Mary and her fellow judge Paul Hollywood.
Comedienne Jo Brand also joins the 'Bake Off' family this year, presenting a new spin-off show, 'An Extra Slice', on BBC Two.
The show will air immediately after the main programme and will feature celebrity guests and an interview with that week's eliminated contestant.

Emmerdale's Doug Potts is to return.
Actor Duncan Preston is to reprise his role more than three years after he last appeared on the ITV soap as Doug returns to the Yorkshire Dales for the wedding of his daughter Laurel Thomas (Charlotte Bellamy).
Viewers will be left wondering if Doug is really back to support his daughter - who is to marry Marlon Dingle (Mark Charnock) - or if he has an ulterior motive.
Duncan commented: "It is lovely to be back in Yorkshire as part of the 'Emmerdale' family. It feels like I have come home and I'm really excited about what is ahead for Doug".
Doug's return could also see him rekindle his romance with Diane Sugden (Elizabeth Estensen), whom he tried to woo before leaving the Dales to reunite with his estranged wife in 2011.
Duncan made his first appearance on 'Emmerdale' in 2007 but took a break in 2010 to pursue theatre work. His temporary departure became a permanent one, however, as executive producer Steve November revealed a return for Doug wasn't definite.
The door was left open for Duncan to return in future and he is expected to be back as a regular character from September.

Plans to include a score by Lily Allen in the new 'Bridget Jones' musical have been scrapped.
The 29-year-old singer recently previewed one of the tracks from the soundtrack - 'Yummy', a love song dedicated to a fridge - but writer Helen Fielding is now re-writing the stage production and no longer requires the 'Not Fair' hitmaker's services.
Lily told The Sun newspaper: "I wrote some great music for it but Helen Fielding wants to go back and write a whole new story.
"It's been a long-term project and I was happy to do my bit but I'm now out of the picture."
The news comes as another blow for Lily, whose return to the pop scene has been beset by problems.
Her 'Sheezus' album debuted at number one in the UK charts, but quickly plummeted thereafter. Meanwhile, her most-recent single releases both failed to make the UK top 40.
Despite this, Lily is refusing to get too downbeat and says that she continues to attract exciting opportunities.
She explained: "I've had two companies come to me and say, 'Have you got ideas?'
"They want me to find a movie that I think I could adapt well and I do have some ideas that I think would work. So my work may make it to the West End yet."

Billy Bob Thornton used to "treat" himself to new boots when he finished work on a movie.
The 'Fargo' actor has given up the ritual now, but admits his closet is bulging with over 50 pairs of footwear.
Discussing a pair of snake-adorned cowboy boots, he said: "I got these in New Mexico a long time ago. I don't anymore, but it used to be when I finished a movie or something, I would always treat myself to a pair of boots. That was always my thing."
Asked how many he owns, he said "1.2 million. No, 50."
Despite being nominated for an Emmy award for his role in 'Fargo', the actor won't be returning for a second season.
He told E! News: "It was such a thrill to do the show.
"I have nothing to complain about. Hopefully, another one that good will come along."
And the 58-year-old actor has an idea of what he'd like to do next, though his ideal role would be in now-defunct teen TV show 'Saved by the Bell'.
Asked what he would like to guest star on, he laughed: "'Saved by the Bell' is not on anymore, so I think I missed my chance.
"There's so much good stuff on TV. Maybe I can play what's his name? Hoder on 'Games of Thrones', the guy who only says, 'Hoder.' Maybe I could be his cousin or something, his long lost cousin."

Jennifer Lopez thinks Maksim Chmerkovskiy is "very hot".
The 'On the Floor' hitmaker - who has twins Max and Emme, six, with ex-husband Marc Anthony - has been romantically linked with the professional dancer since splitting from Casper Smart earlier this year, and though friends admit the pair have been on dates, they are taking things slow and put their friendship first.
A source told E! News: "She does not want to get her kids involved in meeting another guy yet.
"This is so new. There has been a date here and there, but really they are good friends before anything else. Maks asks her for advice and she thinks he is super-talented and very hot. Obviously that is hard to ignore."
While things may not be romantic between them yet, the 45-year-old beauty - who has been married three times - is said to be "open" to finding lasting love.
The source added: "They do text and communicate and she is open to dating in general right now.
"She still believes true love exists and wants to find that someday."
Meanwhile, Maksim has confirmed he is leaving 'Dancing with the Stars'.
Speaking on 'The View', he said: "I'm done dancing. I'm done with 'Dancing with the Stars.' I'm blessed. I'm very honoured. Inside, I'm genuinely honoured."
"I feel like I've done a lot and not enough for me. I looked at last season and I fell in love with the show ... I'm taking up a huge spot and I don't want to do that anymore."
Asked if he is leaving because Jennifer needed his services, he just smiled and laughed in response.
