tere aane se dil ko ye kya ho gaya.
salman khan is singing this song in the movie london dreams.
does anyone know where I can get this song en the lyrics from this song?
Is this what you're talking about?

I haven't seen the film, nor have I heard any of the songs for this movie, so I don't know whether this bit was added into another song or not, but I've searched the soundtrack for the movie on google, and I didn't find any song by this title. I'm assuming that this bit was used just for this part of the movie and wasn't recorded as a full song in the album. I'll use this video to write out the short lyrics for you though and I'll provide a transaltion just in case you need it.
Tere aane se dil ko yeh kya ho gaya?
What has happened to my heart upon your arrival?
Mera dil jo yahaan tha, kahin kho gaya.
My heart that was here has been lost somewhere.

I hope that helps.
