Lady GaGa is taking a selection of saucy underwear on tour so she can make raunchy video calls to boyfriend Taylor Kinney.

The 26-year-old 'Poker Face' hitmaker - whose 110-date Born This Way Ball world tour kicks off in Seoul, South Korea, on Friday (27.04.12) - has packed a few of the 'Vampire Diaries' actor's favourite pieces which she plans to wear for him during their long-distance video catch-ups.

A source told The Sun newspaper: ''Gaga and Taylor have a very physical relationship.

''While Taylor will go to see his girlfriend when he can, they are going to be spending a lot of time apart. She reckons this is going to be the best way of staying close to each other.''

The eccentric singer has also bought a stray cat for her 29-year-old beloved, to stop him from getting lonely while she's away.

An insider said: ''Taylor loves cats and Gaga wanted to give this stray cat a home.

''She has already named it Polly. She has given the pet to Taylor so he can love it forever and really cherish it.''
