Jennifer Lawrence caught a flight out of Los Angeles International Airport on Friday, and the 24-year-old actress was headed to the BFI London Film Festival, where she will be premiering Serena in a few days. So what's she doing in the meantime? Hanging out with boyfriend Chris Martin, natch! The musician is currently in the U. K. working on new music, but we're thinking the two will have all weekend to themselves...

And speaking of Chris, apparently things are going quite well for the new couple. In fact, OK! Magazine claims that the two are taking things to the next level and getting engaged as soon as the Coldplay singer finalizes his divorce from Gwyneth Paltrow! "Jen is talking engagement, babies, the whole nine yards," a source tells the mag. "She's been totally swept off her feet by Chris and is convinced they've got what it takes to go all the way."

Woah there! They've only been dating since July, and seeing as both Martin and Lawrence split from their respective partners months before that, it seems a little quick...
