The 1D member reportedly welcomed his 20th birthday minus the extravagant party and the star-studded guest list in favor of a quiet and romantic one-on-one celebration with a special someone, reports the Daily Record.

Harry Styles turned 20 on February 1 and he allegedly chose to spend it with rumored steady girlfriend, Kendal Jenner. In fact, the 1D member and the 'Keeping Up with the Kardashians' star are serious enough with their relationship for daddy Bruce Jenner to allow the rumored couple to spend a romantic birthday night at his Malibu mansion.

According to the Daily Record, Harry and Kendall spent the 1D member's birthday at Bruce's £5million clifftop mansion in California after the reality star determined the superb view suitable for the intimate celebration.

"Kendall was really keen to make Harry's birthday a memorable one. Her dad Bruce owns an ­incredible clifftop holiday home in California which has amazing views," an unnamed source told the Daily Record.

"The secluded house is perfect for them to spend quality time together. It's also ideal for a party with Kendall's sisters," continued the Daily Record's source.

Harry allegedly wanted nothing more than a one-on-one quality time with love interest, Kendall Jenner, says Hollywood Life. "The fact that Harry just wanted to be with Kendall on his big day speaks volumes about how close they're getting," says the Hollywood Life report.

However, based on the 1D member's Twitter feed, he spent his birthday celebration simply "sitting around."

"Just sitting around being 20," @Harry_Styles tweeted on his birthday.

A grander second celebration is reportedly also on its way, says the Daily Record. And of course, the alleged organizer is no less than his rumored girlfriend, Kendall, who has teamed up with Harry's BFF, DJ Nick Grimshaw.

Although no details about the upcoming party have been announced yet, the Daily Record says that Harry's second birthday bash will most probably be held in London and will mostly likely include Harry's bandmates and celebrity pals Pixie Geldof, Kelly Osbourne and Lily Allen.
