19 teasers of Lena’s 40th birthday bash on ‘The Fosters’

“Unexpected news may keep it from being a truly happy celebration,” according to Freeform.

Maybe trouble is brewing, but dang it if Mike doesn’t look sharp in his John Travolta-style suit.

It’s been a hot minute since Jenna Paul’s been around — you know she’ll be the life of the party.

Of course Lena’s mom is going to be there for the big bash.

Dana is poised to drop some knowledge on Cortney.

What will she have to say about the Cortney/Brandon romance?

Whenever she has to say, looks like Cortney is not having it.

The moms are so cute together.

Are Brandon and Stef ready to move on from the Cortney drama?

This battle seems far from over.

Stef isn’t about to let her disappointment in Brandon ruin her night with Lena.

Taking this moment to point out how amazing Callie’s ’70s throwback outfit is.

Aaron is here to crash the soiree.

Sorry, AJ/Callie shippers — Aaron isn’t going anywhere anytime soon.

He may be crashing, but it appears Aaron has a reason to show up at the party.

Hopefully there’s some info in those papers that will help get Kyle the aid he needs.

AJ doesn’t look very happy about Callie getting close to Aaron.

We’re rooting for AJ and Callie, but this isn’t looking good.
