Talk about being conflicted! Seems Gwyneth Paltrow is really just doing the best she can in her efforts to save the environment ... the Goop guru has a Tesla, after all!

But she and new hubby Brad Falchuk and their kids all took a private jet to Cabo for the MLK holiday weekend which didn't exactly help with their carbon footprint. But hey, what are they supposed to do? Fly commercial?!

The Clean Plate author and her clan were south of the border celebrating Billionaire Boys Club producer pal Crystal Lourd's birthday. The pair wore matching silver sequined spaghetti-strap dresses for a Mexico blowout -- the photo of which Gwen captioned: "Well, you did it again @cl5star!' Thank you for your incredible generosity, spirit and sparkles."

Gwen's and Brad's kids were along for the ride, enjoying the long weekend out of school. Moses is a spitting of his dad Chris Martin and Apple didn't fall far from her mother's tree!
