Lady Gaga is indeed part of the new American Horror Story. Her presence brings a certain level of star power and drama to the series. It's quite exciting for fans.
There are some intense and provocative scenes in 'American Horror Story' with Lady Gaga, but it's important to note that the show often uses such scenes for artistic and plot - related purposes rather than pure shock value. However, the term'sex scene' might be a bit of a simplification as the scenes are usually more complex and intertwined with the overall dark and twisted narrative of the series.
In 'American Horror Story', Lady Gaga has made an impact with her acting. But when it comes to sex themes, the show has its own independent exploration of such topics which are not directly related to Lady Gaga. The show uses horror, drama, and unique characters to tell its stories. Lady Gaga is there to add to the overall aesthetic and narrative quality, not to be a vehicle for sex - themed content. Her characters might be involved in relationships or situations that have some adult undertones, but that's secondary to the main horror - based plot.
