Michelle Obama's former assistant, Kristen Jarvis, is getting hitched to President Obama's former secret service agent, Shaun West -- and our White House sources tell us Malia and Sasha will be standing by Kristen's side as bridesmaids.
We're told the couple dropped $300k on a D'Concierge wedding planner ... which means the whole thing is first class and elegant. Entertainment will feature R&B stars Ledisi, Eric Benet and Kenny Lattimore ... as well as DJ B-Hen.
Michelle will be there along with her daughters, but we're told POTUS is not expected to attend.
18-year-old Malia is now 6'1" ... so our money's on her to grab the bouquet.
