It looks like trouble in paradise once again for on-off couple Demi Lovato and Wilmer Valderrama!
Today, Demi had a very public meltdown on Twitter about relationships, communication, and trust and it sounds like the rant could be easily directed at Wilmer!
Demi tweeted:

So much for a romantic getaway, a la Jelena and Haylor!
While there had previously been reports swirling around that Demi Lovato and her ex BF, Wilmer Valderrama, were spotted on a tropical vacay together in the Bahamas, it sounds like that just isn't the case!
Perhaps she really WAS just headed back from El Lay, after spending the holidays with her fam in Texas!
Demi's rep says:

Whaaaa?!? Are things back on between Demi Lovato and Wilmer Valderrama??
A romantic tropical vacay together may just be the latest adventure for the on-and-off couple!
After spending some time with her family in Texas for the holidaze, Demi mysteriously tweeted out the day after Christmas:

We are still in shock after yesterday’s news that Mexican banda singer and domestic violence awareness advocate, Jenni Rivera, was taken away from us too soon in a plane crash.
However, the Latina icon will not be forgotten.
Following the the heartbreaking news, many celebrities, friends and fans shared their reactions via Twitter. Among those grieving are:
The Jonas Brothers continued their reunion tour last night, with the start of their one THREE nights in El Lay!
The boys took the stage at the Pantages Theater in Hollywood and sang some of their old favorites like, Burnin’ Up and S.O.S., along with their new music and a few covers in between!
Nick surprised the crowd when he started singing Rihanna’s Diamonds… and the audience joined right in!
Check out the Jonas Brothers (above) with their RiRi rendition!
SO beautiful!!! Loves it!
Though, nothing really made up for the fact that Demi Lovato never stepped on stage for a surprise duet! Even her ex(?), Wilmer Valderrama was there!
We were so holding out hope for a Camp Rock reunion!

Lindsay Lohan may be a reckless driver, has perhaps lied to authorities, and possesses some of the stickiest fingers in Hollywood, but underneath it all… she's just a girl lookin' for love!
In a recent interview, the Elizabeth Taylor impersonator revealed that she envied the tumultuous, intense love that Liz shared with Richard Burton, and just wants to find that special kind of amore with another human being.
Lilo shared:
This ain't no X Factor shiz!
Demi Lovato wants you to vote for what's REALLY important!
