On Thursday night, Harry Styles hit London with a beautiful blonde on his arm.

Who was his mystery date for the Another Man A/W launch? His older sister Gemma Styles, of course! Harry, who is still rocking cropped locks, posed with Gemma at Albert’s Club for the celebration.

In Another Man‘s special three-cover issue, Gemma penned an essay revealing what it’s like to be a sibling of a pop superstar. But she’s no slouch, herself. Here are five things you need to know about the elder Styles.

1. She’s a writer

Gemma works as a contributing writer for the U.K.’s The Debrief, penning fun blogs like “Could You Handle Dating a Royal?” The trendy 25-year-old shares her opinions on technology and millennials, bad social media habits and online dating.

She also writes for MTV U.K., covering similar topics about the social consciousness.

2. She has a boyfriend

Gemma has found romance with Michal Mlynowski, who debuted on her social media in January of this year.

But does little brother Harry approve? He’s certainly watching over Gemma. In fact, last fall, during a concert, Styles paused the show to warn his sister that even while performing, he’s on high alert.

“I’m sorry if I seem distracted,” he told the crowd, according to Billboard. “My sister’s here on a date, and I’m trying to keep an eye on it.”

3. She’s a college grad

When Gemma graduated from Sheffield Hallam University in 2013, Harry was right by her side. Sheffield is a public university in South Yorkshire, England.

Of the momentous occasion, the former One Directioner wrote, “She’s all clever and that.”

4. She’s a fashionista

Followers of Gemma’s social media presence already know that the Brit’s got a knack for fashion, but she also shows off her sartorial sensibilities through a cool Tumblr site: gemmastyles.com.

Style staples? Lately, Gemma’s been feeling the ’90s vibes, including “platform trainers,” and “the kind-of sport luxe thing, it’s quite casual — it’s clothes for getting stuff done, bomber jackets,” she told Nobody’s Child in May.

5. She’s started a movement

In conjunction with Nobody’s Child, Gemma launched the #GirlCrush movement earlier this year. The idea? Pushing women to appreciate “the substance of a person” — just not their Instagram pics — Gemma said.

“For me, a girl crush doesn’t have to be someone ‘perfect’: women are real, and flawed, and incredible — those I aspire to be like are the people who accept themselves, have talents and are unapologetic about who they are. (It’s pretty hard to do.),” she explained.
