Just a few months ago, there were rumors that there was trouble in paradise, but now Jennifer Aniston and Justin Theroux are reportedly teaming up for a script.

Theroux, who wrote "Iron Man 2," has supposedly persuaded Aniston to write a comedy with him. At first, she didn't want to write because she has no experience in this field, Expose Entertainment said.

A source said, "They worked out a story idea and a list of characters, and when Justin went away on job for a week, Jen was so inspired she just kept on writing -- alone."

But it appears not everything is happy between the two, and now teaming up has caused tension.

"Jen got the message loud and clear, shrieking, 'Are you kidding me? You're the one who pushed me to do this. I told you I wasn't a writer.' Justin wisely zipped it as Jen angrily ripped up her pages and stormed off."

Aniston previously hinted that the two could get married in 2015. The couple has been engaged for two months.

Another project Aniston is sort of involved with is something being described as Spanx for the face.

Aniston backs beauty company Living Proof, which is working on Neotensil. It's a clear adhesive that goes under the eyes and gives the appearance of taut skin, CNN said.

Neotensil was built off of Dr. Betty Yu's trademarked product, Strateris, which works a lot like Spanx. The effects last for 16 hours.

"A lot of what we do at MIT is fundamental work that can be applied across the board," said MIT professor Robert Langer, where the technology in Living Proof gets its start. "By making new polymers, you can solve all kinds of things, whether it's cancer or gene therapy or haircare."
