Someone from Jennifer Aniston's site won tickets to the Premiere in London and here is what she posted:
My Marley and Me Experience
It was most likely the best hour of my life, I couldn’t believe Jen was right there in front of me, it was so bizarre and surreal, it only sunk it when I left the cinema. unless you’ve had the privilege to see or meet Jen you can really put it into words what it feels like, i thought id be screaming and waving frantically trying to get her attention, but i just stood there; jaw dropped at speechless, shes 100x as Gorgeous in person and shes so so tiny!!
I didn’t manage to get an autograph as her body guards wouldn’t let anyone that close on the carpet, I did however get loads of photos and videos which I will start up loading soon.
where to start.
I got to liecester square about 4 and even then there were over 100 people ready at the stands so I was kind of relieved I had a ticket lol. After a phone call to Helen

I got my premiere ticket at around 6.15, Jen and Owen weren’t due till 6.30 but the woman told me I should wait will 6.45(with a wink) to walk down the carpet, as we all know Jen is most likely always late

! We walked down to the entrance, I had my ticket, camera and Jennifer Aniston collection to the ready! ( at this point the crowd was bordering down the next street!) we waited there for about 10 minutes when one of the guards told us to move as the car was coming, there then was a wave of screams as the car drove down the opposite side to me ( they must gave come drove into the other entrance), I couldn’t see anything at this point but then realised there was a screen above me, I only saw Owen get out of the car and assumed Jen was in another car so I was ready to wait, then Owen turned round and underneath his arm was woman with her back turned away from the camera with what I could see was a blue dress, i could tell by the lose wavy blonde locks it was JEN! I think I went into a panic of ‘OMG OMG OMG’
As soon as Jen and Owen has walked around to there interview stands they opened the gate for all the ticket holders, as I walked through I could see Jen about 10 metres away from me, I suddenly got really nervous and shaky! Jen and Owen were in the middle of the live BBC interview ( you can see me walking past lol) i managed to get a few photos and sneak behind some of the guards where I got as close as I could! ( About 2 metres from the ) cept there was a crowd of people surrounded both J and O so the guards were ushering us all to get in the cinema. Jen looked around to see all of us hoverers standing around them, she looked so calm as if it didn’t bother her in the slightest. After a minute of gormlessly staring at her trying franticly to take as many pictures of her as I could we were made to move into the cinema. There were 6 screens showing altogether and i was in 6, as well and the free drinks and packet of mars planets we got to watch the live feed from the premiere

!! They showed Jen and Owen walking and being interviewed for over an hour, we were able to take a camera inside with us so I was able to get loads pictures in videos of her speaking and signing autographs.
It was so cute, Jen had her black jacket on while posing for shots (as it was bloody freezing) but i dont think she realised she had it on until she put her hands up and said 'wait' smiling to the paps as she took the jacket off.
After Jen and Owen walked in the cinema the certain closed and I was expecting the movie to start, I was abit miffed that I couldn’t get an autograph but I still couldn’t believe JENNIER ANISTON WAS 2 METERS AWAY FROM ME!
The movie was scheduled to commence at 7.30 but it was over 10 minutes late, we were all wondering what was happening. At about 7.45 one of the hosts came in from the side door( which scared the C*** out of me), I assumed she was just going to introduce the movie. She asked us how we all were doing and whether we were excited, i wasn’t really paying much attention until she raised her voice and said ‘ ID LIKE TO INTRODUCE THE STARS OF THE SHOW, OWEN WILSON AND JENNIFER ANISTON’ I couldn’t believe it ‘whaaatttt?!!’, I asked my sister to repeat what she just said! I thought i was going to pass out from heart failure!
There was a raw of clapping at ‘woos’ as Owen walked in he was waving at us all in response, i don’t know when Jen was at this point, probably running late lol! The host as a question like ‘Any words you would like to say to the Marley and me viewers?’, I couldn’t remember exactly what Owen said as I was to anxious for Jen to arrive!, it was something like ‘ I hope you enjoy the movie..etc’. after about 20 seconds JEN WALKED IN!!! I suddenly started clapping and ‘wooing’- actually no SCREAMING franticly! She had such a gorgeous smile, I couldn’t believe I WAS IN THE SAME ROOM with her. I tried to get my camera to work and film her, but then forgot the bloody cap was still on by the time i got it off I realised I had no space left! Typical !!! the host asked Jen the same question and she replied ‘ Ye, just enjoy the movie, I hope you like it ..,’ there were some other comments but I was wasn’t able to make them out, I was too much in shock. They both walked about smiling and waving saying ‘Bye’ !

I wish I had shouted something to get there attention, but the words had gone right out of my mouth!
The movie then started :], I think J and Owen went out after seeing us and didn’t stop for the film.
This sounds like so much fun. Wish I could have been there!
