R&B star Ginuwine has dismissed reports he was under the influence of drugs during a bizarre performance on U.S. Tv last week (ends19Jul13), insisting he was simply suffering from dry eyes.

The Differences hitmaker, who previously battled substance abuse issues, sparked gossip he had slipped back into his bad habits when he appeared to be blinking uncontrollably and acting awkwardly throughout a performance with his Tgt bandmates Tyrese and Tank on early morning show The Couch.

But the singer has since blamed the odd Tv appearance on the lack of moisture in his eyes, writing on Twitter.com, "Obviously I need eye drops..."

He then made light of the incident, joking, "I'm going to always perform in the morning so I can blink blink blink blink blink" and pal Tyrese also joined in the fun, tweeting, "Fellas, ya'll (sic) gotta get it together.... My performance was great... Please guys... Lol (laugh out loud) @TheRealTank @Ginuwine lets get u some eye drops (sic)!"
