Rob Lowe has a lot to be proud of, both personally and professionally. The 49-year-old "Parks and Recreation" star celebrated a major milestone May 10, which he shared with his 634,000 Twitter followers. "Celebrating 23 years sober tonight," Lowe wrote. "It works if you work it." The actor spent the past week surfing in Oahu's North Shore, which he documented via the social networking site.

The "West Wing" alum and married father of two quit drinking in 1990 when he entered a rehabilitation clinic, which he described in his 2011 memoir "Stories I Only Tell My Friends" as "one of the most exhilarating, liberating and exciting four weeks of my life."

Lowe elaborated on his rehab experience while promoting his book during a May 2011 appearance on CNN's "Piers Morgan Tonight." "It was great. I loved it. Because I was ready," the actor said. "Problem is, people go into rehab and they're not ready. You want to get sober for your parents, you want to get sober for your job, you want to get sober for the cops, you want to get sober to protect your image. A lot of good reasons, by the way, but unfortunately, the only thing that works is that you have to want to get sober for you."

He continued, "I was ready. And so if they told me, 'Hey, Lowe, you've got to go stand in the corner on your head,' I would have done it."

NBC's "Parks and Recreation" was recently renewed for a sixth season. Lowe also appears in the HBO drama "Behind the Candelabra," premiering May 26 at 9 p.m. EST.
