Leona Lewis Lets Loose at Mahiki

Looking to relax and blow off some steam, Leona Lewis was spotted hitting up the Mahiki nightclub in London, England last night (June 14).

The “Bleeding Love” songstress looked a bit worn out as she made her exit, sporting a black top, blue skirt, and black boots.

Earlier in the evening, Leona took the stage at the sold-out O2 Arena for another concert on her Labyrinth tour.

During the course of the set list, Lewis stopped to show her appreciation for her fans. "It really is a dream come true and I couldn't have done it without everyone here."

Adam Lambert: "If I Had You" Video Premiere!

Continuing to push forth with his successful post-Idol career, Adam Lambert has dished out another brand new video for his fans' viewing pleasure.

The latest offering happens to be Lambert's new single, "If I Had You," which delves into the political arena a bit.

With the song having debuted on VH1.com, Lambert tells of the tune, “"Basically, what it's saying is no matter what color your skin is, no matter what religion you are, no matter what your sexuality is ... we can all party together. And all this other stuff — money, success, fortune, fashion, glam — it's all great, but it doesn't mean anything if you're not connecting."

Adam adds, “Over the past year, in addition to my unbelievable opportunities, I have also been faced with the unique challenge of staying positive in light of some critics and closed mindedness. My friends, family, and my devoted fans have been a key force in keeping me grounded."

Lady GaGa: "Alejandro" Music Video!

Making it's much-anticipated debut, Lady Gaga released her “Alejandro“ music video earlier today (June 8)!

Directed by photographer Steven Klein, the "Poker Face" singer's latest work is the first collaboration between the pairing - as it's Klein's first music video ever.

Tweeting a heads up of the release, GaGa wrote last night: "Premiering... Tuesday the 8th. 9amPST/12pmEST/5pmGMT. GAGAKLEIN: ALEJANDRO. X Mother Monster."

Having already drawn comparisons to Madonna's "Vogue," the song comes from the 24-year-old's 2009 studio album The Fame Monster.

Chris Brown Denied Entry into the UK

With things not going as planned, Chris Brown has been forced to postpone the UK leg of his world tour.

Scheduled to kick off his concerts in Glasgow on Wednesday night (June 9), the announcement comes as the "Kiss Kiss" hitmaker was denied a visa to enter the country.

With tour promoters scrambling to straighten out the situation, the denied entry comes as a result of Brown's conviction over the assault of ex-girlfriend Rihanna.

A press release from the London Home Office read: "We reserve the right to refuse entry to the UK to anyone guilty of a serious criminal offence. Public safety is one of our primary concerns. Each application to enter the UK is considered on its individual merits."

Meanwhile, the 21-year's promoters, SJM, said: "Due to unforeseen circumstances the Chris Brown UK tour... has unfortunately been postponed."

Christina Aguilera: Bionic Promotional Princess

Continuing to promote her new album Bionic (in stores today), Christina Aguilera was spotted arriving at ABC Studios in New York City this morning (June 8).

The “Come on Over Baby” songstress looked to be in good spirits, having just performed on the “Today” show a few hours earlier.

In related news, Christina recently called off her tour, citing the fact that she hasn’t had enough time to work on the production, with distractions like film and family.

She explained, "I put on a big show. I create sets, costumes. There's major choreography and dance numbers. All of that goes along with a huge production. And I started to feel this is not the right time. It'll be a much better and bigger show when I have time to properly plan."

Once finished up with the gig, Miley was given a boxing robe to cover up with as she was quickly ushered to the backstage area and out to an awaiting ride.

The G.A.Y. performance comes as Miss Cyrus continues to promote her latest album, Can't Be Tamed, in Europe.
