Lady Gaga 'Yoko Ono Call Was Most Exciting Thing Ever'

Lady Gaga was blown away when Yoko Ono personally called her to praise her recent performance of John Lennon's classic 'Imagine'.

The 'Poker Face' star sang the peace song at the Human Rights Campaign's official dinner in Washington, D.C. this month, in support of gay rights.

But instead of simply covering the track, Gaga altered some of the lyrics to commemorate Matthew Shepard (a student who sadly died in the late 90s for being homosexual).

After the performance, Ono praised the 'Paparazzi' hitmaker by writing on her blog and now Lady Gaga has revealed Yoko also gave her a call.

"That could be the most exciting thing that's ever happened. She's my idol." She said.
