Gwen Stefani reportedly met with her estranged husband Gavin Rossdale to carry out the final formalities left for their divorce, Hollywood Life reported Monday. The news comes amid rumors that Stefani and her boyfriend Blake Shelton may have got engaged.

According to Hollywood Life, Stefani was pictured sitting in her car before departing the place where she met with Rossdale. The report also claimed that the "Make Me Like You" singer had a sad look in her eyes as if she was trying to hold back her tears.

“She seemed really upset. They were always very cool and friendly but she definitely seemed different,” a source told Entertainment Tonight. “She seemed distant and sad.”

Hollywood Life reported that Rossdale did not seem to share the same feelings as Stefani as he looked relaxed after meeting his ex-wife. The 50-year-old reportedly waved to paparazzi on his way out of the meeting place.

Stefani and Rossdale, who have three sons, finalized their divorce in April, putting an official end to their 13 years of marriage.

After splitting with Rossdale, Stefani began her romance with Miranda Lambert's ex-husband Shelton. Stefani and Shelton first addressed dating rumors last November, and since then the two have been surrounded with several marriage rumors.

Most recently, rumors surfaced that Stefani and Shelton have got engaged. However, Gossip Cop debunked the report.

Last week, OK! Magazine published a photo of Stefani showing off a baby bump. According to the report, the 46-year-old is “due on her 47th birthday,” in October. However, Gossip Cop debunked that report too.

In January, a report claimed that Stefani, who has three sons with her former husband Gavin Rossdale, was supposedly expecting twins, while in April, OK! Magazine reported that Stefani was a “pregnant bride,” planning her “secret” wedding to Shelton in Oklahoma.

However, the all the pregnancy reports were debunked by Gossip Cop.
