What would Travis Barker and Shanna Moakler be without a little drama?
"We're not together, but we're really good friends," Moakler told PEOPLE about ex-husband Barker while she attended Saturday's White Party, hosted by Diddy
and Ashton Kutcher
to benefit Malaria No More
. "We have a real love for one another, and we always have."
"Travis is leaving for tour, my babies are going with him, so I'm getting all prepared," says Moakler. "We're lucky that Blink  tours are very lavish. We each have our own buses. At the venues, we set up kid rooms so the kids can kind of get out of the buses and start running around. We have a runner to take [them] 'round. They're going to be going to Canada, to see the different parts of the States … so it's pretty exciting."
Divorced since last year, Moakler, 34, and Barker, 33, have two kids, Landon and Alabama. The notoriously up-and-down couple made headlines as recently as three weeks ago, when Barker wrote on his Twitter page
that he didn't like "deadbeat moms that sleep all day" and further opined that "kids are not to be used as weapons."
Such strife appears to be set aside, at least for now, however.
Come July 24, Blink 182 – the pop-punk band popular in the late '90s – begins a 48-city reunion tour through the U.S. and Canada that is due to finish in October. As drummer for the band, Barker has also been active recently with his TRV$-DJAM side project. After his near-fatal plane crash
last summer, Barker is eager to resume his glory days with the band, Moakler says.
"I was there when the band separated, and I really saw all the heartbreak in all the fans," Moakler says. "I saw how upset all the kids were. I watched the different band members go their separate ways, and it was really kind of a sad time in our lives. We were still having babies, but it was kind of an end of an era so to speak. So having them come back together, they're just excited and happy about
it. That's awesome."
