Taylor Swift is apparently a qualified love guru.

The singer recently made the Forbes 100 Most Powerful Women List for the first time, thanks to her massively successful music career.

Her love life has also been a talking point over the years, and she's been linked to everyone from Harry Styles to Jake Gyllenhaal. Taylor's past experiences has meant she's always on hand to help her girlfriends out when they need dating advice, and she's even allegedly gained a qualification in love coaching.

"Taylor is very good at offering advice. She's secretly trained to be a love coach and was doing a course online. She qualified last month," and insider told British magazine Grazia.

"Taylor has drawn up an 'ex rulebook' as a go-to reference for her friends who have recently split up with someone. She's also very good at advising her girl group on how to get more commitment from a man. She's telling Jen [Lawrence] how to deal with her relationship with Chris [Martin], especially because he spends so much time with Gwyneth [Paltrow, ex-wife]."

The source says Jennifer even refers to Taylor as her "man coach".

Lena Dunham, Selena Gomez and Karlie Kloss are also in Taylor's gal pal circle and have all praised her in the past.

The 25-year-old seems to have put her love coach advice into good use recently, as she's been linked to Scottish DJ Calvin Harris since the Brit Awards in February. The romance is said to be going from strength to strength and he's been a rock since her mother Andrea was diagnosed with cancer.

"They're completely loved up. He's been there throughout her mom's illness. He's been an amazing support to her. There are things in her life that are really tough right now, but she's never felt more centred and solid and that's down to Calvin - and her friends," the source said.
