It looks like the National Enquirer, once again, was right on the money. New reports confirm the report earlier this month that troubled singer Whitney Houston’s close advisors and familly are scheduling an intervention as rumors of erratic behavior plague her comeback tour. And get this: Bobby Brown, once Whitney’s partner in crack, has agreed to help.

Though Whitney Houston’s official camp denies the fading diva has fallen off the wagon and blames her recent concert problems on health-related issues, I’m hearing some longtime close Houston friends and family members suspect otherwise.

A veteran associate of the superstar told me Tuesday, ”a couple of us are even seriously thinking of flying to Europe — now that we can [referring to the Icelandic volcano] — and facing Whitney in person and figuring this out.

”We have known her for so long, we will know immediately if she’s using again.”

• The source said even Houston’s ex-husband Bobby Brown — who himself long struggled with drug addiction — has been approached about reaching out to his former wife. Brown reportedly has been clean and sober for quite some time and supposedly is open to helping Houston.

• Though Houston’s reps admit the singer is frustrated that her voice is failing her — and disappointing her many fans — they claim the entertainer is working through all of it and will soon be back on track.

• Another BZ [ed.note: Bill Zwecker] source, who saw Houston at Claridge’s Hotel in London the other night, reports the singer ”was visibly upset and seemed kind of out of it … talking, or rather jabbering, nonstop to the people she was with.”

Meanwhile there are more reports from Whitney’s tour about her once-soaring voice that is now struggling. In her concert earlier this week in Tobago, Whitney only performed for 30 minutes and had a hard time hitting high notes throughout the concert.

R&B diva Whitney Houston disappointed a sold-out crowd who came to see a rare performance by the trouble-prone singer at the Plymouth Jazz Festival in Tobago on Sunday, April 27.

The ‘Greatest Love of All’ singer performed on the last night of the festival, just before headliner Rod Stewart took the stage.

Houston opened her show with ‘Its Not Right, But Its Okay’ and by her third song, ‘Saving All My Love,’ the once soprano’s newfound tenor tone was in full rasp.

Delivering only seven songs during her 30 minute set, Houston was reportedly paid a whopping $3 million for the show.

Though journalists were flown in from all over the world, Houston refused to allow media and photographers within 200 feet of the stage. She brought her own photographer to the venue and only he was allowed to shoot her performance.

Wearing a white gown with a single shoulder strap, Houston skipped around the stage and continuously shouted to the crowd: “I love you Trinidad!’

Unfortunately, the concert was in Tobago!

It is sad to see that years of abuse have ruined one of the greatest modern R&B voices. There was a time when Whitney’s vocals could smoke anyone. Now, she can’t even make it through a half hour set. It’s a shame. And if the reports of this intervention are true, it needs to happen soon. If she keeps blowing these concerts and disappointing her fans, I doubt she will get another shot at a comeback.
