Conor McGregor hit Longitude for his 30th birthday and was mobbed by fans

He only just announced that he is expecting his second child with his long-term partner.

But Conor McGregor understandably left pregnant Dee Devlin at home while he hit Longitude to mark his 30th birthday.

The Dubliner was seen enjoying a beer as he mixed with the festival crowd on Friday - and he happily shared snaps of his day on Instagram on Saturday evening.

Conor seemed to have an area beside the main stage cornered off for him and his mates, which is to be expected considering he was mobbed by fans while walking among the crowds earlier in the day.

He was at least accompanied at all times by some pretty serious-looking security guys.

McGregor is evidently a fan of a summer festival in his native city; he was at Forbidden Fruit last month too.
