Laura Marano is desperate for Sir Paul McCartney to make a guest appearance in 'Austin & Ally'.The 16-year-old singer-and-actress - who portrays Ally Dawson in the Disney sitcom - is a ''huge'' fan of rock 'n' roll music and would love it if the Beatles legend, Sir Mick Jagger or Brian May starred in the programme, but she admits it would be tough to concentrate because she would be so starstruck. She exclusively told BANG Showbiz: ''It's never going to happen but I really want Sir Paul McCartney to guest star in the show because I'm a big, huge Beatles fan - like, it's ridiculous. ''I would love it if Sir Mick Jagger could be in the show, too, because I'm also a big fan of the Rolling Stones. The world of showbiz is surrounded by music and everyone in the cast either plays instruments or sings and we are constantly singing the 'Austin & Ally' songs. ''I'm a big Queen fan, too. It would so cool if Brian May appeared on the show, you have no idea. I don't even know if I would be able to do my job properly because I would be so starstruck, so maybe it wouldn't a good idea. I'm such a huge closet rock 'n' roll fan so it would be so cool. ''It would be ridiculous to collaborate with these guys as well. It would be so cool, you have no idea!'' As well as Laura's TV career - which has seen her appear in 'Dexter' and 'Heroes' - the Disney star has also starred in a number of movies including 2007 comedy film 'Superbad' alongside Jonah Hill and Michael Cera, and she insists the comical Hollywood duo are also ''really, really funny'' off-screen. She added: ''They are really, really funny guys. Everybody from the movie was all super, super cool. 'Superbad' was a really fun experience. It would be pretty hilarious if they starred in 'Austin & Ally'.'' Laura stars in 'Austin & Ally' every week on Disney Channel. The 'Austin & Ally' soundtrack album is out 29 October.
