Katherine Schwarzenegger has got her younger brother's back.
As plenty of people continue to share their opinion on 21-year-old Patrick Schwarzenegger's spring break pictures -- in which he's pictured embracing a bikini-clad woman, and also appears to do body shots off her -- in light of his relationship with Miley Cyrus, Katherine took to Twitter on Tuesday to hit back at his haters.
After retweeting Patrick's message that "Girls have guy friends and guys have friends that are girls...," Katherine, 25, also went on the offensive with this tweet.

But perhaps most telling about her thoughts on the situation is when she responded to a follower who insinuated that the spring break pictures were "insensitive" of Patrick.
"Uhm, those pics though. I'd say my bf was insensitive if he was doing those things w/ another girl ;)" the Twitter user wrote, to which Katherine responded, "Ever heard of spring break?!"
Though Miley has yet to directly respond to the cheating rumors, according to E! News, Patrick is "devastated" by what the reaction has been to the questionable photos. He has already taken to Twitter to explain that the woman in question is actually one of his best friends' girlfriends, and that he would "NEVER do anything against" the 22-year-old "Wrecking Ball" singer.
