Two bookmakers suspend betting on the group playing Glastonbury after several cryptic messages cause a storm on Twitter.
A series of cryptic tweets from former Oasis frontman Liam Gallagher has provoked a frenzy of speculation the band could reform.
He spelled out the band's name in a series of five messages on Twitter on Thursday night.
Gallagher followed this up with another tweet that simply said: "Oasis LG."
Many fans took the tweets as evidence the group is getting back together, and the messages have since between retweeted tens of thousands of times.
Bookmakers Ladbrokes and Paddy Power have suspended betting on the band headlining Glastonbury as a result.
Oasis, which included Liam's brother Noel on lead guitar and vocals, enjoyed worldwide success before an acrimonious split in 2009.
Noel quit after an altercation with Liam, bringing to an end one of the most famous and successful partnerships in British rock history.
It is almost 20 years since the release of the band's debut album, Definitely Maybe, which went straight to number one.
Last year, Liam said he would be willing to "bury the hatchet" and get back together to mark the anniversary.
