After touring the Oval Office, J.Lo and Marc got glammed up for the Congressional Hispanic Caucus Institute's black-tie gala, where Marc was receiving the Lifetime Achievement Award.
While the president was presenting his award, he said Jenny's hubby is quite popular with Latina Congress members.
"I'm telling you, J.Lo, watch out," Obama joked from the podium.
The Obamas weren't their only political powerhouse companions...
Justice Sonia Sotomayor also joined their table during the fancy soiree.
Last month, Jennifer threw the newest Supreme Court justice a dinner party at her house.
After the gala, the couple changed and headed to the W Hotel in D.C., where J.Lo helped Marc blow out the candles on a huge chocolate cake. Sounds like one sweet day!
Obama had some less complimentary words for Kanye West, in case you didn't hear.
