Nate Berkus and Jeremiah Brent
Leave it to an interior designer to know a good plan when he sees one.
Reality TV personality
(and Oprah Winfrey
pal) Nate Berkus tells PEOPLE why – and when – he decided to marry Jeremiah Brent.
"I've known since our first date that Jeremiah was who I wanted to spend the rest of my life with," Berkus, 41, says.
"As we've shared the news of our engagement and been met with so much excitement and support we're both reminded of how important it is that every person have the legal right to marry the one they love."
Berkus popped the question
Monday and the couple celebrated with friends in Peru atop the famed Machu Picchu.
The author of The Things That Matter
, Berkus gained fame after he was invited in 2002 to do a makeover on a space for The Oprah Winfrey Show
and went on to host The Nate Berkus Show
2010 to 2012.
