Rihanna rides the subway in London today

You’re probably wondering why pop singer Rihanna always rides the subway when she’s in London, England. The answer is simple: she’s a nobody in London — also known as a commoner. We Londoners don’t place celebrities and other famous people on pedestals the way you Americans do. As a society, in London, we value the contributions of teachers and doctors.

A celebrity’s talents are appreciated in London but Londoners don’t hype or idolize stars like we do here in the states. Seeing a celebrity such as Rihanna riding the subway train in London is a common occurrence. We yawn at celebrity sightings in London.

Chris Brown Rips WWE Champ -- You Have INFERIOR Man Junk

WWE heavyweight champion CM Punk has a dysfunctional wiener ... this according to Chris Brown.

The two are now in a full on Twitter war ... after Punk randomly tweeted that he wants to "curb stomp" Brown at an upcoming WWE event because he wants Brown to "fight somebody that can defend themselves."

Brown caught wind of the tweet ... and decided to fire back with a message of his own ... writing, "@CMpunk needs more followers. He's such a leader! Not to mention the roids hes on has made it utterly impossible for him pleasure a women."

And in his trademark sarcastic tone ... Brown added, "@CMpunk contact my assistant and I'll have em send u an autographed pic for my biggest FAN!!!"

So far, Punk has not responded to the steroid allegations ... or the suggestion that his man parts don't work ... but Punk has long stated that he's never touched a drug or steroid in his life.

Unreleased Nicki Minaj freestyle

Pre-Barbie footage of Nicki Minaj surfaced online over the weekend. Oddly enough, the footage shows the young Queens MC paying homage to her predecessors, Lil Kim and Foxy Brown. In the video, Minaj strolls down the streets of Queens spitting her “Dirty Money” freestyle.

This video also lends support to those who say Nicki is the butch lesbian rapper in the legendary “eat the box” clip, which you can view here.

Watch Nicki’s “Dirty Money” freestyle after the break.

Tamar speaks on husband Vince’s illness on BFV

In tonight’s episode of WEtv’s Braxton Family Values, Tamar Braxton is forced to face the possibility of life without her beloved husband, Vince Herbert, who is stricken with a deadly illness. As you know, Vince was diagnosed with a pulmonary emboli — a blood clot in his lung which traveled from his leg (DVT).

Tamar, who is usually fiery and outspoken, is reduced to tears as she opens up about the emotional toll of Vince’s serious illness.

Despite her grief, I couldn’t help but notice that Tamar’s face appears to be dry — as in, no actual tears fall. I’m a stickler about fake tears, especially in reality shows. I could be wrong. But something tells me that this scene was filmed just recently.

Watch the video clip after the break.

Tina Knowles: ‘Blue Ivy doesn’t look like Beyonce or Jay Z’

It can’t be good when a grandmother doesn’t recognize her daughter’s

features in her own granddaughter. Tina Knowles spoke with PEOPLE magazine during the Runway to Win Fundraising reception for President Barack Obama last night.

When asked about her granddaughter, Knowles began by cryptically saying, “She’s doing great.”

Well, we would hope the baby is doing great — unless she has some type of hereditary illness that we don’t know about.

Knowles clarified by saying “She’s beautiful.” Then when she was asked pointedly who the baby resembled the most, Tina said: “She’s only a month old. So we have to give her a minute.”

Let’s pause here to reflect on her answer… what grandmother doesn’t recognize her own daughter’s features in her grandbaby? Unless the baby isn’t Beyonce’s — which we already figured.

Most grandmothers would say the baby has her daughter’s eyes, or her son-in-law’s lips, or something.

You mean to tell me Tina doesn’t recognize any resemblance at all in the baby’s features after an entire month?

Basketball Wives Season 4 Equal More Drama

Get More: Basketball Wives (Season 4)

‘Basketball Wives‘ season 4 promises to be just as pointless as season 3. We already know that Evelyn Lozada and Jennifer Williams will have manufactured beef. And when Evelyn isn’t busy jawing at Jennifer, she’s planning her manufactured-for-TV wedding to NFL bench rider, Chad Ochocinco. Oh, and I wonder if Evelyn will mention that her reported spin-off series with Ocho was sacked because VH1 refused to green light it?

Kim Kardashian is a changed woman

This photo of disgraced reality TV personality Kim Kardashian was snapped earlier this week when Kim was on her way to Bible study with her new bestie, singer Leann Rimes. (I guess La La Anthony was busy).

Kim has dedicated herself to bagging the very religious Denver broncos quarterback Tim Tebow by pretending she’s spiritual, prayerful and virginal. On Sunday, she even tweeted that she was on her way to church — something she has never tweeted before.

Luckily, Tim is not as dumb as Kris Humphries – Kim’s hapless ex-husband of 72 days.
