Jenna and Barbara Bush, Then and Now

We remember their party-hearty ways and their crazy college years, but the Bush twins, Jenna and Barbara, have long since grown up. While Jenna has stayed in the media spotlight—she just announced her pregnancy on NBC's "Today" show, where she works as a correspondent—Barbara has kept a lower profile, living in New York City and working on poverty and global health issues. Here's a look at what the former first daughters have been up to. - Lylah Alphonse, Senior Editor, Yahoo Shine

"I'm nervous and so excited to say that Henry and I are pregnant—or I'm pregnant," Hagerannounced on NBC's "Today Show," where she has worked as a correspondent since 2009. "We're so excited. And I'm, you know, obviously nervous about it. I'm a first-time mom—but it's something I've always wanted."

While Jenna has been honing her journalism career -- she was recently named an editor at Southern Living Magazine -- Barbara has been working as the CEO and co-founder ofGlobal Health Corps , a non-profit that helps poor communities in Africa and in the United States.

Both Jenna and Barbara have ties to UNICEF. Jenna wrote a book about her experiences as a volunteer with the organization in Latin America, and Barbara interned for UNICEF in Botswana and is member of their Next Generation Steering Committee. Here the sisters are together at the UNICEF Snowflake Ball.

The twins live separate lives now, but they're both based in New York City ("I'm kind of like a homesick Texan living in New York," Jenna recently told the New York Times) and they often attend charity events, like this year's SickKids Bliss Ball, together.

Though she hasn't spent as much time in the public eye, Barbara Bush has been plenty busy since she graduated from Yale in 2004. She's on the board of directors of Forum's Young Global Shapers, Covenant House International, PSI, and Friends of the Global Fight for AIDS, TB, and Malaria.

Jenna Bush became a correspondent for NBC's "Today" show in 2009. A year earlier, Barbara co-founded and became CEO of Global Health Corps.

Before co-founding Global Health Corps, Barbara worked in Educational Programming at the Smithsonian Institution's Cooper-Hewitt National Design Museum.

Jenna Bush married Henry Chase Hager in 2008. Her wedding was a huge Texas event, and her parents threw a reception for her at the White House afterwards.

During a recent conference—"The Enduring Legacies of America's First Ladies"—Jenna confessed that she shared her first kiss with her now husband after they climbed up onto the White House roof.

Barbara Bush has moved far away from her father's Republican platform. In 2011, she endorsed same-sex marriage, going so far as to tape a video calling on her adopted home state of New York to legalize it. "I am Barbara Bush, and I am a New Yorker for marriage equality,” she said in the video. “New York is about fairness and equality. And everyone should have the right to marry the person that they love.

The twins were always close growing up, and now they live just one subway stop away from each other in New York City. But they both "work incessantly," Jenna told People Magazine, so they don't spend as much time together as they'd like.
