Briana Jungwirth's stepmother fears having a baby with Louis Tomlinson will "ruin" the stylist's life.
The 23-year-old beauty is around three months pregnant with the One Direction hunk's first child and Karen Lawrence is worried about the backlash she has already received from the group's fans.
She said: "I'm distressed for all the c**p I've read online in the middle of the night.
"It's exciting for us and, you know, it's unusual and very strange. But last night in the middle of the night in my anxiety I was like, I'm not gonna look again, because it's too weird these days, what things are said on Twitter, it's just crazy stuff.
"I just hope all this doesn't ruin her life, I care about that, we are at the beginning of something and she's a private person, she's not a Facebook person or anything like that.
"This is really scary for someone in her condition [being pregnant], especially when she's only 23, I think it's pretty overwhelming."
And Briana's dad, Joe Jungwirth, admitted his daughter is having a "tough time" coping with all the attention.
He told Daily Mail Online: "Briana's really shy, she's strong but shy, she's tough but shy and she's having a tough time with it, it's stressing her out right now, she's texting me all the time."
Briana is currently staying in a hotel, reportedly paid for by Louis - who she is not in a relationship with - and his team.
Joe added: "Now that she's out of her mother's house she's a little bit better but she really doesn't like any of this stuff."
