Britney Spears hit a crossroads while watching The Boy Next Door! The "Ooh La La" singer raved about Jennifer Lopez's acting chops after seeing the thriller.

"It's easy for us moms to feel dull and invisible at times but this put some pep in my step. Thank you, Jennifer, for being you," Spears, 33, tweeted on Friday, Jan. 23. "Just saw the new movie 'Boy Next Door.' @JLo is so beautifully strong and inspiring…"

Lopez, 45, retweeted the sweet message, and also got some free promotion out of the deal. "Remember to go see #BoyNextDoor this weekend," Spears added, along with the trailer.

Lopez portrayed an English teacher and new divorcee in The Boy Next Door. Claire's one night of passion with hunky young neighbor Noah (Ryan Guzman) soon turns into a nightmare when he becomes her student — and stalker. (Us Weekly's film critic Mara Reinstein gave the film 3 out of 4 stars!)

Spears and Lopez have a lot in common, both juggling tireless careers, often high-profile romantic relationships, and having two children each. Spears shares sons Sean, 9, and Jayden, 8, with her second ex-husband Kevin Federline. The "Booty" singer" is mom to twins Maximilian and Emme, 6, with her third ex-husband, Marc Anthony.
