Lady Gaga has revealed the identity of her “real life hero”.

The 28-year-old Applause singer began dating boyfriend Taylor Kinney in 2011 and the Chicago Fire actor turned 33 years old on July 15.

In a touching tribute to her beau, she announced on Twitter just how much he means to her.

“Happy Birthday to my darling ?@TaylorKinney111 ? he plays a hero on TV but in real life he's my Hero,” Gaga wrote on Wednesday to her over 41 million followers.

Earlier this month the songstress was spotted shopping at a couture wedding boutique in Toronto, Canada.

And although speculation is rife she is planning on marrying Taylor very soon, apparently she didn’t visit the store to prep for a wedding.

"Lady Gaga is very artistic and yes she bought some white dresses in the bridal section,” an alleged eyewitness told E! News.

“However, she never mentioned it was for a wedding or anything.

"She bought two rolling racks full of vintage clothes and accessories. She bought robes, gowns, hats, jewellery. Some of the designer brands she bought were Dior and Balenciaga. She also bought 1920s and 1930s vintage."

Gaga has addressed marriage rumours in the past directly, noting she’d rather go with the flow at this time.

“Could be, who’s to say,” she told Extra recently of whether she will marry soon.

“I don’t have my life planned that way, I am actually more than ever truly trying to live in the moment and really just enjoy this time right now with you, this time with my team, with my new puppy [Asia], with ARTPOP.”
