The rocker opened the festival with his band Beady Eye in front of thousands of fans last Friday morning and although he stayed for most of the day and evening he didn't camp at the music event.
Liam was joined at the festival in Somerset, South West England, by his wife Nicole Appleton, their son Gene, and his kids Lennon and Molly - his children with ex-wife Patsy Kensit and singer Lisa Moorish respectively - and he admitted having his family with him curbed his usual hellraising antics.
He said: "I couldn't have stayed the night. I'd probably get seriously messed up and leave my kids or something. I don't want to wake up and start brushing my teeth in beer again."
During their storming set - which featured songs from their new album 'BE' - Liam, 40, dedicated Oasis track 'Rock 'n' Roll' star to Lennon.
Following their acclaimed Glastonbury performance, Beady Eye have announced a UK tour.
The 'Flick of the Finger' rockers will hit the road in November kicking off proceedings on November 10 at Glasgow's Barrowlands before heading around the country stopping off for two nights at Manchester's O2 Academy and finishing at London's Hammersmith Apollo on November 21.
Liam and his bandmates - Gem Archer, Andy Bell, Chris Sharrock and Jay Mehler - will also perform at several festivals, including V Festival, T in the Park Japan's Summersonic event.
