Sarah Paulson feels like a ''dog in a window panting'' around Lady GaGa.

The 'American Horror Story' actress is a self-confessed ''super fan'' of the 'Applause' hitmaker, who is set to play the lead role in the new season of the show.

Sarah, who has appeared in the last four seasons, enthused: ''I am just such a super fan. I need to tone it down. I need to start playing it really cool.

''We all know that everybody who likes somebody, that they have to play a little hard to get ... I'm just like a dog in a window panting, waiting to be around her. It's just really pathetic.''

The actress thinks Gaga will be ''incredible'' in her first major TV acting role. Gaga has previously had small parts in movies 'Machete Kills' and 'Sin City: A Dame to Kill For'.

Co-star Sarah told ''I'm in awe of her talent and I really think she's going to be an incredible addition to the show. I just think she's a perfect fit. I can't wait to have that experience [of working with her]. But you know, I'm a fan before I'm anything else, that's for sure.''
