Ne-Yo: I want to collaborate with Kanye and Obama

“He has a pretty good singing voice,” Ne-Yo said of Obama.

The president has been known to occasionally break out into song on the campaign trail, crooning a bit of Al Green’s “Let’s Stay Together” at a fundraising event in New York’s Harlem borough in January.

Ne-Yo noted that if he was able to assemble the president and West for a collaboration, they would have to sing about something other than politics.

“[Politics] doesn’t make for very good songs,” he said.

{mosads}Don’t tell West that, though. The opening track of the rapper’s forthcoming album “Cruel Summer” includes a dig at Republican presidential nominee Mitt Romney.

“I’m just trying to protect my stacks,” West raps. “Mitt Romney don’t pay no tax.”

Also being honored at the Angels in Adoption event by Sen. Mary Landrieu (D-La.), the Congressional Coalition on Adoption co-chairwoman, was actress Katherine Heigl and her husband, singer Josh Kelley.

The Hollywood duo has two adopted daughters — Naleigh, their oldest from South Korea, and Adalaide, who was adopted from Louisiana earlier this year.

“The most beautiful part about becoming parents and having these children is that they ground you in a way you could never have imagined before them,” Heigl said.

Heigl and hubby declined to talk politics, but noted, “The beauty of [this event] is it’s a bipartisan issue.”
