Gwen Stefani's tense reunion with Gavin Rossdale

Gwen Stefani looked tense and visibly upset as she was spotted meeting up with her ex-husband Gavin Rossdale on Thursday (12May16).

The pair, who split last year (15), was seen meeting up in Beverly Hills. The 46-year-old former Voice coach was seen looking stone-faced and agitated while driving away in her car after the 45-minute meeting with Bush frontman Gavin, Entertainment Tonight (ET) reports.

"She seemed really upset," an eyewitness told ET. "They were always very cool and friendly but she definitely seemed different... She seemed distant and sad."

While Gwen seemed to be upset after the reunion, Gavin, 50, appeared relaxed and even waved to waiting paparazzi as he drove away.

The pair's divorce was finalized last month (Apr16) after 13 years of marriage and three children - nine-year-old Kingston, seven-year-old Zuma, and two-year-old Apollo. The couple split following allegations of Gavin infidelity.

"If I could, I would just tell you everything, and you would just be in shock," she said back in March (16) about their split. "It's a really good, juicy story."

According to legal documents from the divorce settlement obtained by ET, the family home will have to be sold and the profits split between the couple - a move that has reportedly upset the former No Doubt frontwoman, who is said to be unwilling to uproot her brood by moving house.

The former couple will continue to share physical and legal custody of their three boys, and Gavin, who was entitled under California law to a 50 per cent stake of all the money Gwen earned while the two were married, refused to take any money that she had acquired on her own.

Gavin has a reported net worth of $35 million , while Gwen is reportedly worth $120 million .

The singer has been dating country star Blake Shelton since last November (15). The pair, who met while they were both judges on The Voice, debuted their duet Go Ahead and Break My Heart on the talent show on Monday (09May16).
