Ain’t it funny.

While many are speculating that a potential baby bulge is the reason behind Jennifer Lopez’s abrupt departure from the big screen version of Dallas, an insider who tattled to the New York Post’s Page Six claims it wasn’t her tummy causing the trouble. Although she hasn’t publicly commented about what prompted her send-off from Southfork, there’s speculation that J. Lo was less than impressed with both her weighty co-star John Travolta and what’s rumored to be a script worthy of Gigli-like comparisons.

"The script sucks," the source told the tabloid matter-of-factly. "And John Travolta? If it had been a man's man like Ed Harris or Tommy Lee Jones . . . but you don't just go from doing Hairspray to Dallas." Or apparently, if you're Jennifer, from Jersey (Girl) to Dallas, either.
