The two new pals bonded over dinner at a get-together in Gwyneth Paltrow's home a while ago, Us Weekly claimed. "Jen and Sandra are new BFFs. They're very excited about the new friendship," an insider told the publication.

Sandra Bullock's commencement speech advice is awesome >>

Aniston and Bullock apparently have lots in common and talked about things such as their bad divorces and mutual ex-boyfriends. Both actresses had actually been engaged in the past to Joshua Donovan, and both broke things off with him before either said "I do."

"Sandra and Jen have a lot in common and enjoy each other's company," the source continued. "They have been having each other over for dinner regularly."

The Friends alum and Gravity star do have some differences in their lives, however. Aniston has finally found the love of her life in Justin Theroux, who she's been happily dating for some time. Bullock has remained famously single since her very public divorce from Jesse James some years ago.

However, the Virginia native has found happiness in adopting a baby boy, Louis, soon after her divorce, and the two are often seen out and about enjoying the town together.

While Aniston and Bullock are friends offscreen, the pair have yet to star in a movie together. That might change in the future, though, as there are several rumors floating around that the two new friends may star with fellow actress Cameron Diaz in the ultimate chick flick extravaganza.

No official word has been released on such a film yet, but if it does happen, it will definitely be a flick worth checking out.

Thanks to hilarious movies like Pitch Perfect, we all know Anna Kendrick has some serious comedic chops. She sure isn't showing 'em off here, though. Perhaps she's studying for a more stoic role.

Hey, now. Taylor Swift may be country music's sweetheart, but this anti-smile has diva written all over it. The "I Knew You Were Trouble" singer's anti-smile borders on mischievous.

We're not sure this qualifies completely as an anti-smile — it might be an anti-smile tinged with smirk. Regardless, it isn't the sweet smile we know Ashley Tisdale is capable of flashing.

Let's be honest, people. It wouldn't matter if James Marsden was smiling, glaring or standing on his head singing, "I'm a Little Teapot." He can do no wrong in our book.

If Cate Blanchett has starting flashing the anti-smile, you know it's a bona fide thing. And since pretty much anything she touches turns to gold, it's probably here to stay.

Girls actress Zosia Mamet certainly has a lot to smile about. In addition to her star-turning role as Shoshanna on the hit HBO series, Mamet has several movies in the works. So why the anti-smile, Z?

Sandra Bullock is so sweet that even her anti-smile bears the faintest trace of a genuine smile. If she actually stopped smiling, we're 67 percent certain the world would stop spinning.

Regular smile, anti-smile... it's merely a matter of po-tay-to, po-tah-to to Cody Simpson's legions of screaming fan girls. It all looks equally good to them.

Although she's putting off some seriously tough vibes with that spiked leather jacket and an anti-smile, Kelly Osbourne is actually a charming gal. Haven't you seen her on Fashion Police? She's a-dorable.

We've got to give it to her — Twisted actress Maddie Hasson has one of the best anti-smiles on the block. Furthermore, we dig the fact that she's flaunting another trend: the return of the full brow, à la Brooke Shields circa The Blue Lagoon.

While we're relatively sure anti-smiles don't have the same mental health benefits as genuine smiles, we admit that they do wonders for bringing out Michelle Trachtenberg's cheekbones.

Here's the thing: While Step Up All In cutie Ryan Guzman looks good no matter what, we're partial to his sexy smile. Also, just FYI, it appears he'll be flashing it in the 2016 Jem and the Holograms movie. Score!

House of Cards actress Kristen Connolly is always stunning, and this anti-smiling, red carpet version of herself is no exception. Still, it kinda reminds us of her beleaguered character in Cabin in the Woods.

Robert Downey, Jr. is Forbes' highest-paid actor for second year in a row >>

Bullock's film Gravity brought in more than $716 million worldwide and garnered seven Academy Awards. And even though the actress didn't win the statue for Best Actress, between June 2013 and June 2014, she jumped all the way from seventh place to the top spot on the Forbes list.

Coming in behind Bullock at No. 2 is Jennifer Lawrence, who is in the second-place spot for the second year in a row. JLaw earned an estimated $34 million in the last 12 months. Not bad for Lawrence, who earned less than $1 million for the first film of the Hunger Games series.

Jennifer Aniston is securely in the third spot, with $31 million.

"Thanks to Friends and her endorsement work for products like Aveeno, Aniston can be choosy about her film projects," said Forbes. "Lately she's focused on smaller-budgeted comedies like We're The Millers and Horrible Bosses. Aniston is usually willing to cut her upfront pay for these movies in return for a chunk of the profits. It's a strategy that's paying off."

Aniston's next film, Horrible Bosses 2, hits theaters in November.

Rounding out the top five are Gwyneth Paltrow with $19 million earned, and Angelina Jolie and Cameron Diaz, who tied for fifth place, earning $18 million each. Jolie was in the No. 1 spot in 2013 — earning $33 million — because her paycheck for Maleficent cleared in that 12-month period.

The actresses made the list not only for earnings from their films, but also from endorsements, residuals and advertising.

Despite the high paychecks for these actresses, women in Hollywood continue to make less than the men. According to Forbes, the top 10 highest-earning actors brought in around $419 million combined, while the top 10 actresses on Forbes' list brought in only around $226 million.
