After a week in which it emerged Brittain wanted to stay with County next season instead of joining the Perth club on the two-year deal he agreed in January, Brittain further upset Saints on Sunday when he scored two penalties to earn the Dingwall side a 2-2 draw at McDiarmid Park.
The 29-year-old was reluctant to talk about the situation after the Clydesdale Bank Premier League clash but St Johnstone manager Steve Lomas was more forthcoming.
The Northern Irishman accused County of tempting Brittain to stay with a contract offer, a claim denied by visiting manager Derek Adams, and questioned whether family reasons were the real cause of his change of heart.
Brittain said: "I didn't read anything in the papers. I focused on getting a good week's training and I was ready for the game. It was a bonus for me to get two goals but the boys were magnificent.
"I'm employed by Ross County and have been for four years so I'll continue to give my all.
"I take no notice of what people are saying about me. I'm not bothered about what the perception is of me now.
"People can say what they want but I prefer to ignore that because if you take notice of it then you'll get tripped up."
