Former Ex On The Beach star Megan, 23, joined The Only Way Is Essex mid-way through its 17th series earlier this year, joining best friends Courtney Green and Chloe Meadows in front of the camera.
Megan's now dating co-star Pete Wicks and is one of the most talked about current TOWIE stars.
Speaking to Daily Star, Kate said: "Megan brought loads of drama when she joined the cast and I know the viewers have loved having her on the show.
"To be honest, there was loads of aggro before she arrived anyway but it just made it worse! I get scared of what I'm going to say because then it all just kicks off."
Megan's had plenty of drama since joining TOWIE, including that rumour she'd secretly slept with Jake Hall, which they both insisted wasn't true. She and Pete also faced negativity towards their romance.
Meanwhile, she clashed with Kate after a pub quiz question about the name of Pete's dog led Kate to jokingly call out Megan's name. Kate later said it had been "blown out of proportion" and she hadn't meant to upset Pete at all, it was just a joke.
Kate also told the newspaper she's used to the Essex rumour mill and tries not to let it affect her relationship with co-star boyfriend Dan Edgar.
"There's always cheating rumours but you have to stay strong sometimes," she said.
"There's loads of pressure on us as a couple, and for any couple on the show. It doesn't matter how strong you are, your relationship will always be that much more intense and people will want to break you up or judge your relationship."
