We aren't the only ones sending tons of YAYwaves to the newly-engaged couple Dave Franco and Alison Brie today.

Dave's older brother James Franco too has issued his 'gram-based congrats to the adorable pair, equipped with ring and heart emojis and a wittle bit of baby talk because whether he's 30 or not, Dave will always be James's 'lil bro.

"Congrats Davy and Allison!!! engaged!!!? I WUUUUUV YOU❤️" James wrote on his Instagram page Tuesday (Aug. 25).

(We'll pretend he didn't just misspell his future sister-in-law's first name there, BTW.)

The youngest Franco -- James and Dave also have a middle brother named Tom -- has been dating Brie for over three years, and the pair broke the news of their engagement by default when Brie showed up to her "Sleeping With Other People" premiere on Monday (Aug. 24) night sporting a "Titanic"-shaming rock on that finger.
