Lady Gaga's London pub serenade

Lady Gaga has reportedly serenaded a newly married couple in a west London pub.

The bar in question was The Raven Pub, Chiswick.

The Poker Face singer saw Julie Searle and her new husband toasting each other with champagne and asked them what they were celebrating.

The 24 year old then asked if anyone had a guitar.

A friend of couple raced back to a nearby hostel to get his guitar and Gaga proceeded to serenade the couple with Gimme Shelter by the Rolling Stones in a private back room.
