Solange Knowles doesn't want her three-year-old son, Daniel, to go into the family business.

"I'd love for him to be talented in other things," Beyoncé's 22-year-old little sister says. "I hope that he wants to be a...computer engineer."

Since giving birth to Daniel—when she was just 18—we haven't seen or heard much from Solange...

But these days, she's everywhere, because she has a new album to promote. Her sophomore effort, Sol-Angel and the Hadley St. Dreams, will be released August 26.

This is as fabulous as it gets for Knowles. "I don't have a life in Hollywood," Knowles told me the other day while running errands in L.A. "I don't do s--t. Just work. I come home and take my son to the movies. I don't go out. It's only like the BET Awards or something like that, that I actually do something."

Then there's her serious side. Just look at the video for the new album's first single, the Pharell Williams-written "I Decided." Depicted throughout are archival footage and photographs from key moments in American history, like the Civil Rights movement.

"6 O'Clock Blues," a collaboration with Amy Winehouse's Grammy-winning producer Mark Ronson, hits on Hurricane Katrina and poverty, among other issues.

"I wouldn't say that I'm political, but I'm definitely aware," Knowles said.

But in the very next breath, she cooed, "I do have Obama fever."

She met the presidential hopeful at a dinner not too long ago. "It was crazy because I had all these questions I wanted to ask him," Knowles recalled. "But once I got in the midst of his presence, I totally felt like I was meeting a rock star."

Unlike her obsessively private older sister, Knowles has no problem opening up about her personal life. She married football player Daniel Smith while she was pregnant with their son, but they divorced about three years later. However, she won't let that spoil her dreams of finding love again. "I got married at 17, so I won't judge from that one experience," she said with a laugh.
