One Direction's Louis Tomlinson is easing back into bachelorhood ... by hooking up with multiple chicks at once -- or so it seemed when a pack of at least 3 went to his London hotel room.

Tomlinson was partying at Cirque Le Soir Wednesday night ... before the after-party moved to the Soho Hotel. Best part of the rendezvous -- the girls' walk of shame Thursday morning -- although maybe it's more like walk of fame ... when you've raged with a One Direction singer all night?

Tomlinson broke up with GF Eleanor Calder last month after 4 years together.

Everyone mourns in their own way.

Harry Styles is about to go the way of Zayn Malik -- bolting from the ranks of One Direction ... at least according to acclaimed director and honorary 1Der Morgan Spurlock.

Spurlock directed the docufilm "One Direction: This Is Us" -- which, outside of Simon Cowell, makes him the foremost expert on the band ... among grown men. Morgan told our photog the band will be fine as a foursome for now, but it's only a matter of time before Harry splits.

But even that won't kill the band. Check out Morgan's prediction for Niall, Louis and Liam.

Think flattops -- on white guys. It just might work ...

Zayn Malik broke his silence Friday night -- come to think about it we haven't heard him speak before -- and he heaped praise on his former band, One Direction.

Zayn accepted a trophy at the Asian Awards in London. The award was for Outstanding Achievement in Music. Interesting, because it's the only award Zayn can accept independent of the band. He's getting it because of his Pakistani heritage.

It sounds like there's no beef with the boys.

Zayn Malik has one direction in mind these days ... South, as in the South of France.

The former "One Direction" singer was leaving a hotel with his fiancee Perrie Edwards Friday.

Zayn wants to repair his relationship with Perrie and spend time with his family, which is why he says he left the group.

The South of France is a good place to win just about anyone over.

Four is the magic number for One Direction, because the band has no plans to add a fifth member following the Earth-shattering departure of Zayn Malik.

Sources close to Simon Cowell and the record label tell TMZ ... the band is moving forward with recording their new album sans Malik. As for eventually finding a replacement -- we're told there's "absolutely zero" talk of that.

That being said ... we're told the remaining 1Ders are still talking to Zayn regularly, and the band completely respects his decision to bolt.

One Direction played its first Zayn-less show in South Africa earlier this week. They tour Europe in June before hitting the U.S. in July.

Zayn Malik's face screams "REGRET" in the first pics of him since he quit One Direction -- at least that's how millions of fans see it.

But we have a feeling Zayn will be just fine -- as long as he's cool with the state fair circuit.

Count Justin Bieber as one of the legions of One Direction fans who are broken up because Zayn Malik quit the band.

Biebs was leaving Bar 20 at the Grafton Hotel in WeHo Thursday when our photog gingerly asked how he felt about One Direction-less. Bieber echoed the hurt that millions of tweens are enduring.

Biebs also dropped some big news, although it did seem pretty obvious ... he'll be walking Floyd Mayweather to the ring for the big fight with Manny Pacquiao.

Zayn Malik's face ... hours after he quit One Direction ... said exactly what millions of 1Ders were thinking -- "OMG, what the hell have I done?"

Zayn was out in North London on Wednesday afternoon ... settling into retirement, at 22 years old.

While he reportedly cited "stress" as the reason he originally dropped out of the band's tour -- word is he was worried his lifestyle on the road was messing up his life with his fiancée.

The band plans to continue without him and finish its tour before the next album comes out.

Meanwhile, Zayn will be wondering if he's the next Timberlake ... or the next Kirkpatrick.

Zayn Malik has found a new direction and it's all about stepping out of the spotlight ... he says he's leaving One Direction to be just a regular guy for awhile.

The band announced Malik's exit via Facebook Wednesday but Zayn says even though the last 5 years have been a dream, he needs to go with his gut and chill ... you know, just like every other normal 22-year-old pop icon.

The rest of the group says it's a huge bummer, but they respect his decision and plans to go on as a foursome with Niall, Harry, Liam, and Louis picking up the slack.

Producer Simon Cowell also sang Zayn's praises but he's definitely holding his chin up and assuring the die-hard fans they have nothing to fear -- the band will go on.

As for Zayn's reason to splitsville ... last Thursday he bowed out of the band's world tour due to "stress," but rumors swirled his lifestyle threatened his relationship with his fiance.

The band vows to continue to tour as a lead up to their fifth album.

Kobe did it ... LeBron did it ...and now Harry Styles is also teaming up with the tribe for some good old fashioned athletic competition -- at a Jewish Community Center.

TMZ Sports has learned ... the One Direction star hit up the Westside JCC in L.A. Thursday to play a little indoor hockey with some friends.

We're told Styles was one helluva player -- scoring several goals during the hour-and-a-half long session.

Fun Fact -- there were actually 6 Jews in the NHL last season! Who knew?

Michael Sam is getting support from one of the biggest pop stars in the world -- Harry Styles ... who rocked the football player's jersey during a One Direction concert in St. Louis yesterday.

Harry threw on a #96 St. Louis Rams jersey with Sam's name across the back during the a performance at Edward Jones Dome ... where the Rams play.

It's an interesting move for Styles -- whose bandmate Liam Payne came under fire for his support for the "Duck Dynasty" guys after the reality stars came out against gay marriage.

Zayn Malik from One Direction has dared to go where Rihanna chickened out ... he just tweeted, "#FreePalestine."

The 21-year-old singer -- who grew up Muslim -- posted his comment Sunday night and lots of followers quickly reacted. One posted, "Are you still alive? You should be dead by now and kill yourself." Another said, "You and your family need to die."

Someone -- apparently in Israel -- wrote, "U have fans in #Israel. It broke me that one of my idols wand (sic) me to die."

Malik -- unlike Rihanna -- didn't back down. She removed an identical tweet 8 minutes after it was posted.

One Direction is gunning for the person they say stole a private video showing Zayn Malik and Louis Tomlinson smoking weed.

The video, which appears on MailOnline, shows the guys enjoying a joint while riding around in an SUV while in Peru.

At one point in the video -- shot earlier this year -- Louis is seen passing Zayn the joint and saying, "One very very important factor of Zayn’s warm up of course is Mary J, herself."

A rep for the band tells TMZ the video was stolen and that the band's lawyers are investigating.

Say what you will about Louis Tomlinson, but the One Direction singer's got a serious pair of cojones for taking a stand on one of the biggest arguments in sports -- Messi vs. Ronaldo.

Louis -- who dabbles in pro soccer himself -- was leaving a tattoo shop in L.A. this weekend when we asked him ... who's the better player??! The pretty boy or the Atomic Flea?!

It's a raging controversy in the football world ... here are the cliff notes for the debate:

-- Ronaldo has 38 goals in '13/'14 play ... Messi has 27.
-- Messi outscored Ronaldo by 18 GOALS in the 2 seasons before that.
-- Messi has 13 more assists than Ronaldo over the past 3 seasons.

But ... Ronaldo is bigger where it counts -- his wallet.

According to Goal.com, Ronaldo's worth €148 million ... while Messi's only worth a puny €146 million.

One Direction singer Louis Tomlinson made his pro soccer DEBUT in England last night ... and while his performance was lackluster, dude was OBSESSED with his own beautiful hair.

The 22-year-old pop star hit the pitch for the Doncaster Rovers, a Football League Championship team based in Yorkshire.

Tomlinson entered the game at right back ... but didn't really see much action.

Instead, people at the game say he spent a lot of time flipping his hair around on the field.

Still, the crowd went wild for the guy ... and his team didn't lose -- the game ended in a 0-0 tie.
