She's become one of the most recognised names on the planet since news of her romance with Prince Harry broke.

But if you were to mention Rachel Markle in conversation, it's likely nobody would have a clue who you were talking about.

However, Rachel is in fact the name Prince Harry's girlfriend was given by her parents and the more commonly known Meghan is actually her middle name.

Ironically, Meghan shares her birth name with the character that made her famous - Rachel Zane.

It's unclear whether she ever went by the name Rachel and changed to Meghan as a stage name, or if she's always been known by her middle name.

MailOnline has contacted a representative for Meghan for further comment.

It's not uncommon in Hollywood for stars to change their names to something a bit more glamorous or catchy, and Meghan is in good company with Katy Perry, John Legend and Miley Cyrus.

Storm Keating, wife of singer Ronan, is another public figure who chooses to use her middle name, having being born Sharyn Storm Uechtritz.

In a sign that her relationship with Prince Harry is growing ever more serious, the star attended Pippa Middleton's wedding reception with her royal beau on Saturday evening.

Harry, 33, and his 35-year-old girlfriend drove down to Berkshire early on Saturday morning and the prince attended the wedding ceremony along with his brother William.

While Meghan skipped the ceremony she later joined her boyfriend for the evening reception.

She and Harry were photographed driving up to Middleton's parents' estate for the lavish soiree, which was off-limits to the press.

One photo, published Sunday, showed Harry at the wheel of an Audi with Meghan by his side.

But the smiling Suits star managed to largely duck the cameras to avoid stealing the limelight at the extravagant reception, where she witnessed a spectacular aerial display from a £100,000 glass marquee.

The happy couple joined guests to watch the historic Spitfire Mk V plane soar through the skies against a stunning sunset for ten minutes from the 'porta palace' erected in the Middleton's back garden.

A live band belted out music from the marquee as guests parties the night away, including jazz renditions of Call on Me by Eric Prydz and The White Stripes Seven Nation Army, the Sun reported.

Rumours have been circulating for some weeks that Meghan had been invited to the nuptials despite Pippa's 'no ring, no bring' policy.

However, some believe Meghan may have chosen to stay away from the church ceremony to avoid upstaging Pippa and bringing more attention to her relationship with Harry.

To have her on his arm earlier today at such a high-profile event would once again have re-fuelled suggestions the pair could be set to marry.

It seems that Meghan has been eagerly anticipating the occasion as she has been seen indulging in several beauty treatments in the run up to the big day.

On Friday the actress, who landed in London on Tuesday, was spotted leaving a swanky spa in Soho, London, after a £250 facial ahead of the society event of year.
