Tom Brady can cross sixth member of the Backstreet Boys off his post-football plans ... 'cause AJ McLean says the Pats QB's singing is way too garbage for that.

We brought you the story last week ... TB12 had a date night with Gisele out at U2's concert in Boston when he screeched out the words to "Vertigo" and "Pride (In The Name of Love)."

When we showed AJ the clips ... his reaction was the same as mostly everyone else's ... "Not everybody is supposed to be a singer."

McLean did give props to Brady for sharing his, um, voice with the world ... saying it took "cajones" for Brady to do that.

U2 cancelled a SRO concert in Paris scheduled for tonight in the wake of the deadly Paris attacks.

The cancellation appears to be a reaction to safety concerns. A rep for U2 said, "As a result of the ongoing state of emergency across France, the U2 Paris concert scheduled for 14th November will not be going ahead as planned."

Ditto Coldplay, which cancelled a livestream concert set for the day of the attacks in L.A. Rather than expressing safety concerns, the band said the concert would not go on "out of respect for all the terrible events in Paris."

Penelope Cruz is still hot enough to get U2 to play an entire concert ... JUST FOR HER -- at least that's what 24,000 people must have thought was happening in Barcelona.

Bono and co. played to a packed arena there this week, and when they made the mistake of inviting Penelope and hubby Javier Bardem on stage -- chica snapped pic after pic after pic as the band played on. She even had the lads pose for shots with Javier!

Imagine ... you pay through the nose to see 4 old Irish dudes rock out, and instead you end up with Penelope's bunny-ears-sporting-ass in your face.

Actually ...

Security at a U2 concert in Sweden couldn't find what they were looking for ... a guy with a weapon -- so the band was forced to cancel their show.

Swedish authorities tell TMZ ... Stockholm's The Globen venue was evacuated Sunday night after security lost track of the guy who somehow got inside.

The band was regretful, saying, "The organizers apologize for the inconvenience caused and thank the audience for their understanding. Their safety is the priority."

Chelsea Clinton got wanded just like everyone else at the U2 concert in NYC.

The daughter of presidential candidate Hillary Clinton and hubby Marc Mezvinsky showed up Friday night at Madison Square Garden, and she flashed a faint smile as guards looked for contraband.

It's even more amusing because Chelsea was also there with Eve Hewson, Bono's daughter.

U2's longtime tour manager died early Wednesday morning in Los Angeles ... just as the band kicked off a week-long string of concerts in the city.

Law enforcement sources tell TMZ ... Dennis Sheehan was found unconscious in his room at the Sunset Marquis Hotel. We're told paramedics were called to Sheehan's hotel room around 5:30 AM for a reported cardiac arrest. He was pronounced dead on the scene.

Sheehan -- who was in his late 60s -- has been U2's tour manager for more than 30 years.

His death came just hours after the curtain went down on U2's first of 5 concerts at the Forum in L.A.

The Edge still can't find what he's looking for ... in this case, the rest of the stage.

U2 opened up its "Innocence + Experience" world tour Thursday in Vancouver. As the band played its iconic hit, "I Still Haven't Found What I'm Looking For" ... Edge went flying offstage.

After the show he posted he was fine, writing, "Didn't see the edge, I'm ok!! #U2ieTour." Looks like his arm is badly scraped.

The band is already operating at less than 100% -- Bono suffered a terrible bike accident in NYC last November that required two surgeries.

For months, U2 fans have been waiting for the release of a new album reportedly produced by Danger Mouse.

Wonder who was on the receiving end?

TMZ has obtained photos of Tiger and Tony Romo hanging out in the quarterback's box at Cowboys Stadium during a U2 concert back in October.

The blonde woman next to Tiger doesn't appear to be his wife, Elin Nordegren -- which begs the question, do you think she knew where he was that night?

The magician and the rocker were caught partying together at PURE Nightclub at a pre-Halloween costume bash, though neither of them wore anything out of the ordinary ... well, not for them.

UFC fighter Quinton "Rampage" Jackson was hanging with Angel as well.

Judging from the rather giddy laughter that followed his answer, it's also possible that Bono was just joking, or speaking some wink-winky language only understood by Irish musicians.
