Taylor Swift is showing off what's she's calling her 'new roommate.'  She posted a few pictures on Twitter of her adorable new kitten, Meredith. 

Taylor doesn't say whether or not she's taking her new companion on the road as she continues her 'Speak Now' tour.  She does say, another guest joined her on stage at her show in Houston Texas. 

Taylor has been known for bring special guests on stage to sing with her.  While in Nashville, Kenny Chesney, Ronnie Dunn and Tim McGraw all joined her for a song or two.  Her show in LA brought out teen hearthrob Justin Bieber.

But in Houston, she went from country to rap as Nelly made a cameo appearance.  Taylor Tweeted: 'Singing 'Just A Dream' with Nelly was a serious lifetime highlight. Fantastic night.'

Taylor will soon wrap up her touring for the year.  She has 8 more shows including her 2 night close to the tour in New York City, November 21st and 22nd.  I wonder who she'll bring on stage with her in the Big Apple.  There is plenty of talent there to choose from.

Check out the video of Taylor and Nelly rapping, country style.
