The honeymoon's over already for newlyweds Liam Gallagher and Nicole Appleton - the Oasis singer is off to the U.S. to record the band's new album.

After seven years together and a six-year-old son Gene, the couple finally tied the knot on Valentine's Day at Westminster Registry Office - the same venue Liam wed his first wife Patsy Kensit in 1997.

But after only four days of wedded bliss, Liam has been forced to leave his 33-year-old bride at home in London to join brother Noel and bandmates Gem Archer, Andy Bell and Zak Starkey at a Los Angeles recording studio.

The pair were spotted kissing each other goodbye on the steps of their north London home yesterday as Liam prepared to fly Stateside.

As the newlyweds said their goodbyes, their son Gene - dressed in matching Ugg boots with his mother - seemed more interested in playing on his scooter.

Liam, 35, had been recording the group's seventh album - a follow-up to 2005's Don't Believe The Truth - in LA and temporarily left the band to fly back to Britain specially for the wedding.

Husband and wife: Liam's bride Nicole flashes her wedding ring

Liam's older brother Noel was a noticeable absentee at the nuptials, but Nicole's sister and former All Saints bandmate Natalie and her husband, Progidy star Liam Howlett were in attendance, along with Liam's son Lennon, from his first marriage to Patsy.

Following the civil ceremony, the couple hosted a small soiree at the Landmark Hotel in Marylebone.

A friend of the couple said: "They felt like they were married anyway.

"He's worn a ring on his wedding finger for years to show his commitment.

"But he decided it was the right time and the wedding was completely hush-hush."

Liam and Nicole started dating in 2000, soon after the rocker split from Patsy following three years of marriage.

Liam's troubled marriage to Patsy started on a bad note when it was revealed the singer had conceived a daughter Molly with singer Lisa Moorish just a week after marrying Patsy.

Before meeting Liam, Nicole was previously engaged to Robbie Williams and revealed in her 2002 biography Together that she had an abortion after becoming pregnant with his child.
